                               OFFER TO EXCHANGE

  UP TO $125,000,000 OF  8 5/8% SENIOR SUBORDINATED NOTES DUE 2007, SERIES B
                       FOR ANY AND ALL OF THE OUTSTANDING
              8 5/8% SENIOR SUBORDINATED NOTES DUE 2007, SERIES A
               -------------------------------------------------
                  THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M.,
             NEW YORK CITY TIME, ON        , 1998, UNLESS EXTENDED.
                ------------------------------------------------
     Newpark Resources, Inc., a Delaware corporation ("Newpark" or the
"Company"), hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying letter of transmittal (the "Letter
of Transmittal" and, together with this Prospectus, the "Exchange Offer"), to
exchange an aggregate of up to $125,000,000 principal amount of 8 5/8% Senior
Subordinated Notes due 2007, Series B (the "Exchange Notes"), which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
for an identical face amount of the issued and outstanding 8 5/8% Senior
Subordinated Notes due 2007, Series A (the "144A Notes" and, together with the
Exchange Notes, the "Notes") of the Company with the Holders (as defined herein)
thereof in integral multiples of $1,000. As of the date of this Prospectus,
there is $125,000,000 in aggregate principal amount of the 144A Notes
outstanding. The terms of the Exchange Notes are identical in all material
respects to the 144A Notes, except that the Exchange Notes have been registered
under the Securities Act, and therefore will not bear legends restricting their
transfer and will not contain certain provisions providing for an increase in
the interest rate payable on the 144A Notes under certain circumstances relating
to the Registration Rights Agreement (as defined herein), which provisions will
terminate as to all of the Notes upon the consummation of the Exchange Offer.
The Exchange Notes will be obligations of the Company evidencing the same
indebtedness as the 144A Notes and will be entitled to the benefits of the same
Indenture (as defined herein). The Indenture provides for both the issuance of
the 144A Notes and the Exchange Notes. See "The Exchange Offer."

     Interest on the Exchange Notes will accrue from the date of issuance
thereof and will be payable semi-annually on June 15 and December 15 of each
year, commencing June 15, 1998.  The Exchange Notes will mature on December 15,
2007.  The Exchange Notes are redeemable, in whole or in part, for cash at any
time on or after December 15, 2002, at the option of the Company, at the
redemption prices set forth herein, together with accrued and unpaid interest,
if any, to the redemption date.  In addition, at the option of the Company, up
to 35% of the original aggregate principal amount of the Exchange Notes may be
redeemed on or prior to December 1, 2000 at the redemption price set forth
herein together with accrued and unpaid interest, if any, to the redemption date
with the net proceeds of one or more Public Equity Offerings (as defined herein)
of the Company, provided that at least $81.25 million of the aggregate principal
amount of the Notes remains outstanding following such redemption.  Upon the
occurrence of a Change of Control (as defined herein), the Company will be
required to make an offer to repurchase all or any part of each holder's
Exchange Notes at a cash purchase price equal to 101% of the principal amount
thereof, together with accrued and unpaid interest, if any, to the date of
purchase.  There can be no assurance that the Company will have sufficient funds
necessary to repurchase the Exchange Notes upon the occurrence of a Change in
Control.  The Exchange Notes will not be subject to any sinking fund.  The
provisions of the Indenture allow the Company to incur additional indebtedness,
including Senior Indebtedness (as defined herein), subject to certain
limitations.  See "Description of the Exchange Notes."

                                             (cover page continued on next page)
                         ------------------------

     SEE "RISK FACTORS" BEGINNING ON PAGE 14 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PARTICIPANTS IN THE EXCHANGE.

                         ------------------------

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

                         ------------------------
                 The date of this Prospectus is         , 1998
<PAGE>
 
     The Exchange Notes will be unsecured senior subordinated obligations of the
Company and, as such, will be subordinated in right of payment to all existing
and future Senior Indebtedness (as defined herein) of the Company. The Exchange
Notes will rank pari passu in right of payment with all other existing and
future senior subordinated indebtedness, if any, of the Company (including any
144A Notes that remain outstanding after the consummation of the Exchange
Offer), and senior in right of payment to all existing and future subordinated
indebtedness, if any, of the Company. The Exchange Notes will be guaranteed,
jointly and severally, on a senior subordinated basis (the "Guarantees") by
substantially all of the Company's subsidiaries (the "Guarantors" and, together
with the Company, the "Issuers"). The Guarantees will be unsecured senior
subordinated obligations of the Guarantors and will be subordinated to all
existing and future Guarantor Senior Indebtedness (as defined herein), which
includes all indebtedness under the Credit Facility (as defined herein). As of
September 30, 1997, on an as adjusted basis after giving effect to the 144A
Notes Offering (as defined herein) and the application of the net proceeds
therefrom, the Issuers would have had approximately $129.4 million in aggregate
principal amount of indebtedness outstanding, of which approximately $4.4
million would have ranked senior in right of payment to the Exchange Notes and
the Guarantees, and the Company would have had an aggregate of $88.0 million of
available borrowings under the Credit Facility. See "Description of the Notes--
Subordination."

     As of the date of this Prospectus, approximately 94% of the consolidated
assets of the Company were held by the Guarantors and substantially all the
Company's cash flow and net income was generated by the Guarantors. Therefore,
the Company's ability to make interest and principal payments when due to
holders of the Notes is dependent, in part, upon the receipt of sufficient funds
from its subsidiaries.

     The Company intends to apply for listing on the New York Stock Exchange
(the "NYSE") of the Exchange Notes.  The Company's common stock is listed on the
NYSE under the symbol "NR."

     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of 144A Notes being tendered for exchange.  However, the Exchange Offer
is subject to certain conditions that may be waived by the Company and to the
terms and provisions of the Registration Rights Agreement.  The 144A Notes may
be tendered only in denominations of $1,000 and integral multiples thereof.  The
date of acceptance and exchange of the 144A Notes (the "Exchange Date") will be
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent.  144A Notes tendered pursuant to the Exchange Offer may be
withdrawn at any time prior to the Expiration Date (as defined herein).  The
Company will not receive any proceeds from the Exchange Offer.  The Company and
the Guarantors will pay certain expenses incident to the Exchange Offer.  The
Exchange Offer will expire on       , 1998 (the "Expiration Date"), and the
Company does not currently intend to extend the Expiration Date.

     The 144A Notes were offered and sold on December 17, 1997, at a price of
$1,000 per $1,000 principal amount of 144A Notes, in a transaction not
registered under the Securities Act in reliance upon an exemption from the
registration requirements thereof (the "144A Notes Offering").  In general, the
144A Notes may not be offered or sold unless registered under the Securities
Act, except pursuant to an exemption from, or in a transaction not subject to,
the Securities Act.  The Exchange Notes are being offered hereby in order to
satisfy certain obligations of the Company contained in the Registration Rights
Agreement.  Following the Exchange Offer, any Holders of 144A Notes will
continue to be subject to the existing restrictions on transfer and, as a
general matter, the Company will not have any further obligation to such Holders
to provide for registration under the Securities Act of transfers of the 144A
Notes held by them.

     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that the Exchange Notes issued pursuant to the
Exchange Offer in exchange for 144A Notes may be offered for resale, resold or
otherwise transferred by any Holder thereof (other than any such Holder that is
an "affiliate" of the Company within the meaning of Rule 405 promulgated under
the Securities Act) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange Notes are
acquired in the ordinary course of such Holder's business and such Holder does
not intend to participate, and has no arrangement or understanding with any
person to participate, in the distribution of such Exchange Notes.  Holders of
144A Notes wishing to accept the Exchange Offer must represent to the Company
that such conditions have been met.

                                      ii
<PAGE>
 
     In some cases, certain broker-dealers may be required to deliver a
prospectus in connection with the resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with any resale of Exchange Notes received in
exchange for such 144A Notes where such 144A Notes were acquired by such broker-
dealer for its own account as a result of market-making activities or other
trading activities (other than 144A Notes acquired directly from the Company).
The Company has agreed that, for a period of 180 days after the Exchange Date,
it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."

     The 144A Notes are designated for trading in the Private Offerings, Resales
and Trading through Automated Linkages ("PORTAL") market.  To the extent that
144A Notes are tendered and accepted in the Exchange Offer, a Holder's ability
to sell untendered and tendered but unaccepted 144A Notes could be adversely
affected.

     Prior to this Exchange Offer, there has been no public market for the 144A
Notes or the Exchange Notes.  If a market for the Exchange Notes should develop,
the Exchange Notes could trade at a discount from their principal amount.
Although the Company intends to list the Exchange Notes on the NYSE, there can
be no assurance that the application will be approved. The Initial Purchasers
(as defined herein) have indicated to the Company that they intend to make a
market in the Exchange Notes, but are not obligated to do so, and such market-
making activities may be discontinued at any time.  As a result, no assurance
can be given that an active trading market for the Exchange Notes will develop.

     Except as described below, the Exchange Notes issued pursuant to this
Exchange Offer will be issued in the form of a single permanent Global Exchange
Note (as defined herein), which will be deposited with, or on behalf of, The
Depository Trust Company (the "DTC") and registered in its name or in the name
of Cede & Co., its nominee. Beneficial interests in the Global Exchange Note
representing the Exchange Notes will be shown on, and transfers thereof will be
effected through, records maintained by the DTC and its participants.
Notwithstanding the foregoing, 144A Notes held in certificated form will be
exchanged solely for Certificated Notes (as defined herein). After the initial
issuance of the Global Exchange Note, Certificated Notes will be issued in
exchange for beneficial interests in the Global Exchange Note only on the terms

                                  THE COMPANY

     Newpark is a leading provider of integrated environmental and oilfield
services to the oil and gas exploration and production industry in the U.S. Gulf
Coast area, principally in Louisiana and Texas.  Services provided, either
individually or as part of a comprehensive package, include: (i) oilfield waste
services utilizing patented and proprietary technology, including processing and
disposing of nonhazardous oilfield waste ("NOW") and oilfield waste that is
contaminated with naturally occurring radioactive material ("NORM"); (ii)
drilling fluids products and services and related engineering and technical
services; (iii) mat rentals and sales in which patented prefabricated wooden
mats are used as temporary access roads and worksites in oilfield and other
construction applications; and (iv) other integrated environmental and oilfield
services, including construction, design and engineering services.  In order to
take advantage of many customers' increasing focus on outsourcing and vendor
consolidation, Newpark has integrated its drilling fluids products and services
with its waste disposal and mat services to provide a "one-stop shop" approach
to solving customers' problems.  For the twelve months ended September 30, 1997,
Newpark had total revenues of $194.1 million, and EBITDA (as defined herein) of
$81.0 million.

     Newpark collects, processes and disposes of oilfield waste, primarily NOW
and NORM.  Newpark processes NOW received at its facilities primarily for
injection into environmentally secure geologic formations deep underground and,
to a lesser extent, for disposal at certain landfarming facilities.  NOW that is
not injected or landfarmed is processed by Newpark into a product which is used
as intermediate daily cover material or cell liner and construction material at
municipal waste landfills.  In 1994, Newpark began processing and disposing of
NORM waste.  Since June 1996, Newpark has operated under a license authorizing
the direct injection of NORM into disposal wells at Newpark's Big Hill, Texas
facility, the only offsite facility in the U.S. Gulf Coast licensed for the
direct injection of NORM.

     Newpark is a full-service provider of drilling fluids and associated
engineering and technical services to the onshore and offshore oil and gas
exploration industry in the Gulf Coast areas of Louisiana and Texas.  Newpark
focuses on providing unique solutions to highly technical drilling projects
involving complex conditions, as these projects require critical engineering
support of the fluids system during the drilling process to ensure optimal
performance at the lowest total well cost.  Newpark has established its own
barite grinding capacity to provide a source of critical raw materials for its
drilling fluids operations.  Additionally, Newpark has initiated a process to
recycle a portion of the drilling fluids received as waste in its NOW disposal
business to (i) recover barite and other key chemical components for reuse in
the production of drilling fluids, (ii) reduce the cost of materials in
producing drilling fluids and (iii) expand Newpark's supply of drilling fluids.

     In its mat business, Newpark uses patented interlocking wooden mat systems
to provide temporary access roads and worksites in unstable soil conditions,
primarily in support of oil and gas exploration 

                                       1
<PAGE>
 
operations along the U.S. Gulf Coast. In response to increasing environmental
regulations, in 1994, Newpark began marketing its mat services for use in the
construction of pipelines, electrical distribution systems and highways in and
through wetlands environments. As a result, this new market for Newpark's mat
business has broadened the geographic area served by Newpark to include the
coastal areas of the Southeastern U.S., particularly Florida and Georgia.
Newpark also markets its mat services to the oil and gas exploration industries
in Venezuela and Algeria.

     Newpark also provides a comprehensive range of other environmental and
oilfield services for its customers' oil and gas exploration and production
activities, including site assessment, waste pit design, construction and
installation, regulatory compliance assistance, site remediation and site
closure, construction services, hook-up and connection of wells and installation
of production equipment.

     Demand for Newpark's environmental and oilfield services is being driven by
three significant trends: (i) increasing oil and gas exploration and production
expenditures and activity; (ii) more complex drilling techniques, which tend to
generate more waste; and (iii) increasing environmental regulation of NOW and
NORM.  According to the Baker-Hughes Rotary Rig Count, the number of drilling
wells working in the U.S. Gulf Coast recently reached its highest level since
1990, and the average rig count in the region for the nine months ended
September 30, 1997 was the highest average since 1985.  Newpark believes that
technological advances, including the use of three dimensional seismic data and
computer-enhanced interpretation of this data, have reduced the risk and cost of
finding oil and gas, while improved drilling tools and fluids have reduced the
overall cost and length of time to drill a well.  The oilfield market for
environmental services also has experienced growth due to increased regulatory
activity.  Louisiana, Texas and other states have enacted comprehensive laws and
regulations governing the proper handling of NOW and NORM, and regulations have
been proposed in several other states.  As a result, generators of waste and
landowners have become increasingly aware of the need for proper treatment and
disposal of such waste in both the drilling of new wells and the remediation of
production facilities.

     Newpark's principal executive offices are located at 3850 North Causeway
Boulevard, Suite 1770, Metairie, Louisiana 70002-1752, and its telephone number
is (504) 838-8222.

BUSINESS STRENGTHS

     Proprietary Products and Services.  Over the past 15 years, Newpark has
acquired and developed, and continues to improve, patented or proprietary
technology and know-how which have enabled the Company to provide innovative and
unique solutions to oilfield construction and waste disposal customers.  Newpark
believes that increased customer acceptance of its proprietary products and
services has enabled it to take advantage of the recent upturn in drilling and
production activity.

     Injection of Waste.  Since 1992, Newpark has developed and used proprietary
technology to dispose of NOW by low-pressure injection into unique geologic
structures deep underground.  In December 1996, Newpark was issued process
patents covering its NOW and NORM waste processing and injection operations.
Newpark believes that its proprietary injection technology is currently the most
cost-effective method for the offsite disposal of oilfield wastes.
Additionally, Newpark believes that its proprietary injection technology is
suitable for the disposal of other types of waste, and Newpark recently has
filed an application to expand into the nonhazardous industrial waste market.

     Patented Mats.  Newpark owns or licenses several patents that cover its
wooden mats and subsequent improvements.  To facilitate entry into new markets
and reduce the Company's dependence on the supply of hardwoods, Newpark obtained
the exclusive license for a new patented synthetic mat designed from 

                                       2
<PAGE>
 
recycled plastics and other synthetic materials and has begun the development of
a manufacturing facility to produce such synthetic mats.

     Low Cost Infrastructure.   Newpark has assembled an infrastructure covering
the entire U.S. Gulf Coast region, including injection disposal sites, transfer
stations, barges, mat inventories, mat service centers, hardwood supplies for
the construction of mats, and barite supplies for the make-up of drilling
fluids.  Newpark believes that it owns, leases or has options to acquire a
majority of the available injection disposal sites in the U.S. Gulf Coast
suitable for its proprietary injection methods.  Newpark also owns or leases
under long-term charter 43 of the 53 barges currently licensed to transport NOW
and NORM.  Newpark built a substantial portion of its infrastructure during the
depressed market conditions that prevailed prior to 1996 and believes that,
under current market conditions, its infrastructure could be duplicated only at
significantly higher cost.

     Integration of Services.  Newpark believes it is one of the few companies
in the U.S. Gulf Coast able to provide a package of integrated services and
offer a "one-stop shop" approach to solving customers' problems.  Newpark's mats
provide the access roads and worksites for a majority of the land drilling in
the Gulf Coast market, and on-site and off-site waste management services are
frequently sold in combination with mat services.  Newpark's entry into the
drilling fluids business has created the opportunity for it to recycle used
drilling fluids and to market drilling fluids with other drilling services,
including construction services, related technical and engineering services,
disposal of used fluids and other waste material, site cleanup and site closure.
Consequently, Newpark believes that it is uniquely positioned to take advantage
of the industry trend towards outsourcing and vendor consolidation.

     Experience in Regulatory Environment.   Newpark believes that its operating
history provides it with a competitive advantage in the highly regulated
oilfield waste disposal business.  As a result of working closely with
regulatory officials and citizens' groups, Newpark has gained acceptance for its
proprietary injection technology and has received a series of permits for the
Company's disposal facilities, including a permit allowing the direct injection
of NORM at Newpark's Big Hill, Texas facility.  These permits enable Newpark to
expand its business and operate cost-effectively.  Newpark believes that its
proprietary injection method is superior to alternative methods of disposal of
oilfield wastes, including landfarming, because injection provides greater
assurance that the waste is permanently disposed of and will not contaminate the
surrounding property and groundwater.  Newpark further believes that increasing
environmental regulation and activism will inhibit the widespread acceptance of
other disposal methods and the permitting of additional disposal facilities.

     Experienced Management Team.  Newpark's executive and operating management
team has built and augmented Newpark's capabilities over the past ten years,
allowing it to develop a base of knowledge and a unique understanding of the
oilfield construction and waste disposal markets.  Newpark's executive and
operating management team has an average of 22 years of industry experience, and
an average of eight years with Newpark, including several who have been with
Newpark for 20 years or more.  Newpark also has strengthened its management team
by attracting additional experienced personnel and by retaining key management
personnel of the companies it has acquired.

BUSINESS STRATEGY

     Service and Product Extensions.  Newpark believes that it can apply the
waste processing and injection technology it has pioneered and developed in the
oil and gas exploration industry to other industrial waste markets.  Initially,
Newpark intends to focus on wastes generated in the petrochemical processing and
refining industries, as many potential customers in these industries are located
in the markets already served 

                                       3
<PAGE>
 
by Newpark, and certain wastes generated by these industries have many of the
same characteristics as the NOW waste currently handled by Newpark. In addition,
Newpark will continue to evaluate the applicability of its injection disposal
methods to other industrial waste streams. Newpark is pursuing the development
of a synthetic mat system to enhance its current mat fleet and expand into new
markets. Newpark believes that synthetic mats may have certain military and
emergency response applications.

     Implement Newpark's Total Fluids Management Concept.  Newpark's strategy is
to integrate its operations to provide a "one-stop shop" approach to solving
customers' problems.  By integrating its drilling fluids and waste disposal
services with other on-site fluids management and solids control services,
Newpark intends to provide a comprehensive solution to the management of the
total fluids stream.  Newpark calls this concept "Total Fluids Management" and
believes that its ability to provide a comprehensive package of products and
services reduces the total cost to the customer and increases operating
efficiency.

     Geographic Expansion.  Newpark believes that significant expansion
opportunities exist in each of its product lines, both in domestic markets and
in selected foreign markets.  Newpark intends to expand its oilfield waste
disposal operations domestically into West Texas and the Permian Basin, with
initial international expansions planned for Mexico and Venezuela.  As part of
this strategy, Newpark seeks to continue to add disposal capacity, including new
injection wells, throughout the U.S. Gulf Coast region, in order to more
efficiently serve its customers.  Newpark intends to expand its drilling fluids
business through acquisitions and internal growth to the offshore Gulf of
Mexico, the mid-continent and Permian Basin regions of the United States, and,
internationally, to Mexico, Venezuela and Canada.  In its domestic mat business,
Newpark will continue to capitalize on environmental regulations affecting the
construction of pipelines, electrical distribution systems and highways in and
through wetlands and other environmentally sensitive locations.
Internationally, Newpark intends to expand its mat operations in Venezuela and
Algeria and review expansion opportunities in other parts of Africa, South
America, Europe and Asia.

          Cost Reductions.  Newpark will continue to pursue a strategy of
reducing costs in its existing operations to increase margins.  Newpark intends
to expand the use of washwater recycling facilities and the recycling of
oilfield waste from its NOW disposal business for use in its drilling fluids
business, as these methods will allow Newpark to reduce the volume of waste
transported and disposed of in its injection wells.  Newpark also believes that
recycling of oilfield waste from its NOW disposal business will provide it with
a low-cost source of raw materials for the production of its drilling fluids.
Newpark intends to continue to consolidate supply and purchasing functions in
its drilling fluids business to eliminate duplicate costs, better utilize its
existing asset base and take advantage of manufacturer direct pricing, volume
discounts and direct rail transportation.

                                 registered in the name of a broker, commercial
                                 bank, trust company or other nominee and who
                                 wishes to tender in the Exchange Offer should
                                 contact such registered holder promptly and
                                 instruct such registered holder to tender on
                                 such beneficial owner's behalf. If such
                                 beneficial owner wishes to tender on such
                                 beneficial owner's own behalf, such beneficial
                                 owner must, prior to completing and executing

                                 registered holder. The transfer of registered
                                 ownership may take considerable time, and
                                 completion of such transfer prior to the
                                 Expiration Date may not be possible. See "The

                                 Exchange Offer, Newpark and the Guarantors will
                                 have fulfilled the covenant contained in the
                                 Registration Rights Agreement (the
                                 "Registration Rights Agreement") dated December
                                 10, 1997 among the Issuers, Merrill Lynch,
                                 Pierce, Fenner & Smith Incorporated, Deutsche

                                 (the "Initial Purchasers"), and, accordingly,
                                 there will be no increase in the interest rate
                                 on the 144A Notes pursuant to the terms of the
                                 Registration Rights Agreement, and the Holders
                                 of the 144A Notes will have no further

                                 Registration Rights Agreement. Holders of the
                                 144A Notes who do not tender their 144A Notes
                                 in the Exchange Offer will continue to hold
                                 such 144A Notes and will be entitled to all the
                                 rights and will be subject to all the
                                 limitations applicable thereto under the
                                 Indenture dated December 17, 1997 among
                                 Newpark, as issuer, the Guarantors, as
                                 guarantors, and State Street Bank and Trust
                                 Company, as Trustee, relating to the 144A Notes
                                 and the Exchange Notes (the "Indenture"),
                                 except for any such rights under the
                                 Registration Rights Agreement that by their
                                 terms terminate or cease to have further
                                 effectiveness as a result of the making of, and
                                 the acceptance for exchange of all validly
                                 tendered 144A Notes pursuant to, the Exchange
                                 Offer. All untendered 144A Notes will continue
                                 to be subject to the restrictions on transfer
                                 provided for in the 144A Notes and the
                                 Indenture. In general, the 144A Notes may not
                                 be offered or sold unless registered under the
                                 Securities Act, except pursuant to an exemption
                                 from, or in a transaction not subject to, the
                                 registration requirements of the Securities
                                 Act. To the extent that the 144A Notes are
                                 tendered and accepted in the Exchange Offer,
                                 the trading market for untendered 144A Notes
                                 could be adversely affected.

Absence of Dissenters' Rights
 of Appraisal                    Holders of the 144A Notes do not have any
                                 dissenters' right of appraisal in connection
                                 with the Exchange Offer.

                       SUMMARY OF TERMS OF EXCHANGE NOTES

     The form and terms of the Exchange Notes are the same as the form and terms
of the 144A Notes (which they replace), except that the Exchange Notes have been
registered under the Securities Act and, therefore, will not bear legends
restricting the transfer thereof. In addition, the holders of Exchange Notes
generally will not be entitled to further registration rights under the
Registration Rights Agreement, and the Exchange Notes will not contain
provisions (which currently are included in the 144A Notes) providing for an
increase in the interest rate payable on the 144A Notes under certain
circumstances relating to the Registration Rights Agreement, which provisions
will terminate as to all of the Notes on the consummation of the Exchange Offer.
The Exchange Notes will evidence the same debt as the 144A Notes and will be
entitled to the benefits of the Indenture. See "Description of the Exchange
Notes."

Securities Offered          $125,000,000 aggregate principal amount of 8 5/8%
                            Senior Subordinated Notes due 2007, Series B.

Maturity Date               December 15, 2007.

                            June 15, 1998.

Optional Redemption         The Exchange Notes are redeemable, in whole or in
                            part, for cash at any time on or after December 15,
                            2002 at the option of Newpark, at the redemption
                            prices set forth herein, together with accrued and
                            unpaid interest, if any, to the redemption date. In
                            addition, at the option of Newpark, up to 35% of the
                            original aggregate principal amount of the Exchange
                            Notes may be redeemed on or prior to December 1,
                            2000 at a redemption price equal to 108 5/8% of the
                            principal amount thereof, together with accrued and
                            unpaid interest, if any, to the redemption date with
                            the net proceeds of one or more Public Equity
                            Offerings of Newpark, provided that at least $81.25
                            million aggregate principal amount of the Exchange
                            Notes remains outstanding following such redemption.
                            See "Description of the Exchange Notes--Optional
                            Redemption."

Guarantees                  The Exchange Notes will be guaranteed, jointly and
                            severally, on a senior subordinated basis, by
                            substantially all of Newpark's subsidiaries. See
                            "Risk Factors-- Holding Company Structure; Possible
                            Invalidity of Guarantees; Potential Release of
                            Guarantees" and "Description of the Exchange Notes--
                            Guarantees."

Subordination               The Exchange Notes will be unsecured senior
                            subordinated obligations of Newpark and, as such,
                            will be subordinated in right of payment to all
                            existing and future Senior Indebtedness of Newpark,
                            which includes indebtedness under the Credit

                            Facility. The Exchange Notes will rank pari passu in
                            right of payment with all other existing and future
                            senior subordinated indebtedness, if any, of Newpark
                            (including any 144A Notes that remain outstanding
                            after the consummation of the Exchange Offer), and
                            senior in right of payment to all existing and
                            future Subordinated Indebtedness, if any, of
                            Newpark. The Guarantees will be unsecured senior
                            subordinated obligations of the Guarantors and will
                            be subordinated to all existing and future Guarantor
                            Senior Indebtedness, which includes indebtedness
                            under the Credit Facility. As of September 30, 1997,
                            on an as adjusted basis after giving effect to the
                            144A Notes Offering and the application of the net
                            proceeds therefrom, Newpark and the Guarantors would
                            have had approximately $129.4 million in aggregate
                            principal amount of Indebtedness outstanding
                            (excluding up to $17.6 million of third party
                            indebtedness guaranteed by Newpark), of which
                            approximately $4.4 million would have ranked senior
                            in right of payment to the Exchange Notes and the
                            Guarantees, and Newpark would have had an aggregate
                            of $88.0 million of available borrowings under the
                            Credit Facility. See "Risk Factors - Subordination
                            of the Notes and the Guarantees" and "Description of
                            the Exchange Notes--Subordination."

Change of Control           Upon the occurrence of a Change of Control, Newpark
                            will be required to make an offer to repurchase all
                            or any part of each holder's Exchange Notes at a
                            cash purchase price equal to 101% of the principal
                            amount thereof, together with accrued and unpaid
                            interest, if any, to the date of purchase. See
                            "Description of the Exchange Notes--Certain
                            Covenants--Change of Control."

Certain Covenants           The Indenture relating to the Notes contains certain
                            restrictive covenants, including, but not limited
                            to, covenants with respect to the following matters:
                            (i) limitation on additional indebtedness; (ii)
                            limitation on restricted payments; (iii) limitation
                            on liens; (iv) disposition of proceeds of asset
                            sales; (v) limitation on sale, issuance and
                            ownership of capital stock of subsidiaries; (vi)
                            limitation on transactions with affiliates; (vii)
                            limitation on dividends and other payment
                            restrictions affecting restricted subsidiaries;
                            (viii) limitation on certain other senior
                            subordinated obligations; (ix) limitation on
                            designation of unrestricted subsidiaries; (x)
                            limitation on non-guarantor restricted subsidiaries;
                            and (xi) restrictions on mergers, consolidations and
                            the transfer of all or substantially all of the
                            assets of Newpark. See "Description of the Exchange
                            Notes--Certain Covenants."

Absence of Public Market 
 for the Exchange Notes     There is no public trading market for the Exchange
                            Notes. Although Newpark intends to apply for listing
                            of the Exchange Notes on the NYSE, there can be no
                            assurance that Newpark's

                                       11
<PAGE>
 
                            application will be approved or that an active
                            trading market for the Exchange Notes will develop
                            or continue after the Exchange Offer. Newpark has
                            been advised by the Initial Purchasers that they
                            currently intend to make a market in the Exchange
                            Notes, although they are under no obligation to do
                            so and may discontinue any market-making activities
                            at any time without notice. No assurance can be
                            given as to the liquidity of the trading market for
                            the Exchange Notes or that an active public market
                            for the Exchange Notes will develop. If an active
                            trading market for the Exchange Notes does not
                            develop, the market price and liquidity of the
                            Exchange Notes may be adversely affected. If the
                            Exchange Notes are traded, they may trade at a
                            discount from the initial offering price of the 144A
                            Notes for which they were exchanged, depending on
                            prevailing interest rates, the market for similar
                            securities, the performance of Newpark and certain
                            other factors. See "Risk Factors--Absence of Public
                            Market for the Exchange Notes."

                                  RISK FACTORS

     See "Risk Factors" for a discussion of certain factors that should be
considered by Holders of the 144A Notes before deciding to tender 144A Notes in
the Exchange Offer.

                                  RISK FACTORS

     In addition to the other information contained in or incorporated by
reference into this Prospectus, Holders of 144A Notes should carefully consider
the following factors before deciding to tender 144A Notes in the Exchange
Offer.  The risk factors set forth below are generally applicable to the 144A
Notes as well as the Exchange Notes.

CONSEQUENCES OF FAILURE TO EXCHANGE 144A NOTES

     Holders of 144A Notes who do not exchange their 144A Notes for Exchange
Notes pursuant to the Exchange Offer will continue to be subject to the
restrictions on transfer of such 144A Notes as set forth in the legend thereon
and in the Indenture as a consequence of the issuance of the 144A Notes pursuant
to exemptions from, or in transactions not subject to, the registration
requirements of the Securities Act and applicable state securities laws.  In
general, the 144A Notes may not be offered or sold, unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws.  The
Company does not currently anticipate that it will register the 144A Notes under
the Securities Act.  In addition, upon consummation of the Exchange Offer,
Holders of the 144A Notes that remain outstanding will not be entitled to any
rights under the Registration Rights Agreement that by their terms terminate or
cease to have further effectiveness as a result of the making of this Exchange
Offer.  Although the 144A Notes have been designated for trading in the PORTAL
market, to the extent that 144A Notes are tendered and accepted in the Exchange
Offer, the trading market for the untendered and tendered but unaccepted 144A
Notes could be adversely affected.

DEPENDENCE ON OIL AND GAS INDUSTRY

     Demand for Newpark's environmental and oilfield services depends in large
part upon the level of exploration and production of oil and gas and the
industry's willingness to spend capital on environmental and oilfield services,
which in turn depends on oil and gas prices, expectations about future prices,
the cost of exploring for, producing and delivering oil and gas, the discovery
rate of new oil and gas reserves and the ability of oil and gas companies to
raise capital.  Domestic and international political, military, regulatory and
economic conditions also affect the industry.  Prices for oil and gas
historically have been volatile and have reacted to changes in the supply of and
the demand for oil and natural gas, domestic and worldwide economic conditions
and political instability in oil producing countries.  No assurance can be given
that current levels of oil and gas activities will be maintained or that demand
for Newpark's services will reflect the level of such activities.  Prices for
oil and natural gas are expected to continue to be volatile and affect the
demand for Newpark's services.  Shortages of critical equipment and trained
personnel to operate such equipment also may limit the level of drilling
activity in the oil and gas industry.  A material decline in oil or natural gas
prices or activities could materially affect the demand for Newpark's services
and, therefore, Newpark's consolidated financial statements.

LEVERAGE

     As of September 30, 1997, on an as adjusted basis after giving effect to
the 144A Notes Offering and the application of the net proceeds therefrom,
Newpark would have had approximately $129.4 million of long-term debt (excluding
up to $17.6 million of third party indebtedness guaranteed by Newpark), which
would have represented approximately 33.4% of its total capitalization.  See
"Capitalization."  In addition, the Indenture and Newpark's other debt
instruments will allow Newpark to incur additional indebtedness, including
Senior Indebtedness or secured indebtedness in the future.  As of September 30,
1997, on an as adjusted basis after giving effect to the 144A Notes Offering and
the application of the net proceeds 

                                       14
<PAGE>
 
therefrom, Newpark would have had an aggregate of $88.0 million of available
borrowings under the Credit Facility. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources." Newpark's ability to make payments with respect to the Notes and to
satisfy its other debt obligations will depend upon its future operating
performance, which will be affected by prevailing economic conditions and
financial, business and other factors, certain of which are beyond Newpark's
control. Upon the issuance of the 144A Notes, Newpark's interest expense
increased compared to prior years. Newpark believes, based on current
circumstances, that Newpark's cash flow, together with available borrowings
under the Credit Facility, will be sufficient to service its debt requirements
as they become due for the foreseeable future.

     The degree to which Newpark is leveraged could have important consequences
to holders of the Notes, including: (i) Newpark's ability to obtain additional
financing in the future for working capital, capital expenditures, acquisitions
or general corporate purposes may be impaired; (ii) a portion of Newpark's cash
flows from operations may be dedicated to the payment of principal and interest
on its indebtedness, thereby reducing the funds available to Newpark for its
operations; (iii) certain of Newpark's indebtedness contains financial and other
restrictive covenants, including those relating to the incurrence of additional
indebtedness, the creation of liens, the sale of assets, tangible net worth,
ratio of current assets to current liabilities, ratio of total debt to total
capitalization and ratio of debt service coverage; (iv) certain of Newpark's
borrowings are and will continue to be at variable rates of interest which
exposes Newpark to the risk of greater interest rates; and (v) Newpark may be
more leveraged than certain of its competitors, which may place Newpark at a
relative competitive disadvantage and make Newpark more vulnerable to changing
economic conditions.  As a result of Newpark's current level of indebtedness,
its financial capacity to respond to market conditions, capital needs and other
factors may be limited.

SUBORDINATION OF THE NOTES AND THE GUARANTEES

     The payment of principal of, premium, if any, and interest on the Notes
will be subordinated to the prior payment in full of all existing and future
Senior Indebtedness of Newpark, which includes indebtedness under the Credit
Facility.  Therefore, in the event of a liquidation, dissolution, reorganization
or any similar proceeding regarding Newpark, the assets of Newpark will be
available to pay obligations on the Notes only after Senior Indebtedness has
been paid in full, and there may not be sufficient assets to pay amounts due on
all or any of the Notes.  In addition, Newpark may not pay principal of,
premium, if any, interest on or any other amounts owing in respect of the Notes,
make any deposit pursuant to defeasance provisions or purchase, redeem or
otherwise retire the Notes, if any Senior Indebtedness is not paid when due
(whether upon scheduled repayment, acceleration or otherwise), unless, in either
case, such default has been cured or waived, any such acceleration has been
rescinded or such indebtedness has been repaid in full.  Moreover, under certain
circumstances, if any non-payment default exists with respect to Designated
Senior Indebtedness (as defined herein), Newpark may not make any payments on
the Notes for a specified time, unless such default is cured or waived, any
acceleration of such indebtedness has been rescinded or such indebtedness has
been repaid in full.  See "Description of the Exchange Notes--Subordination."
As of September 30, 1997, on an as adjusted basis after giving effect to the
144A Notes Offering and the application of the net proceeds therefrom, Newpark
would have had approximately $4.4 million in aggregate principal amount of
Senior Indebtedness outstanding (excluding up to $17.6 million in third party
indebtedness guaranteed by Newpark), and Newpark would have had an aggregate of
$88.0 million of available borrowings under the Credit Facility.  Under the
terms of the Indenture governing the Notes, and Newpark's other debt
instruments, Newpark may incur additional indebtedness, including future Senior
Indebtedness or secured indebtedness.  See "Description of the Exchange Notes--
Certain Covenants."

                                       15
<PAGE>
 
     The Guarantees will be unsecured senior subordinated obligations of the
Guarantors and will be subordinated to all existing and future Guarantor Senior
Indebtedness, which includes indebtedness of the Guarantors under the Credit
Facility. As of September 30, 1997, on an as adjusted basis after giving effect
to the 144A Notes Offering and the application of the net proceeds therefrom,
the Guarantors would have had outstanding approximately $4.4 million in
aggregate principal amount of Guarantor Senior Indebtedness. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources," "Description of Certain Other Indebtedness"
and "Description of the Exchange Notes."

HOLDING COMPANY STRUCTURE; POSSIBLE INVALIDITY OF GUARANTEES; POTENTIAL RELEASE
OF GUARANTEES

     The Notes are the obligations of Newpark.  As of the date of this
Prospectus, approximately 94% of the consolidated assets of Newpark were held by
the Guarantors and substantially all of Newpark's cash flow and net income was
generated by the Guarantors.  Therefore, Newpark's ability to make interest and
principal payments when due to holders of the Notes is dependent, in part, upon
the receipt of sufficient funds from its subsidiaries.

     Newpark's obligations under the Notes have been guaranteed, jointly and
severally, on a senior subordinated basis by each of the Guarantors, which
consist of substantially all of Newpark's subsidiaries.  To the extent that a
court were to find, pursuant to federal or state fraudulent transfer laws or
otherwise, that at the time a Guarantor entered into a Guarantee either (a) the
Guarantee was incurred by a Guarantor with the intent to hinder, delay or
defraud any present or future creditor or the Guarantor contemplated insolvency
with a design to favor one or more creditors to the exclusion in whole or in
part of others; or (b) the Guarantor did not receive fair consideration or
reasonably equivalent value for issuing its Guarantee and, at the time it issued
the Guarantee, such Guarantor (i) was insolvent or rendered insolvent by reason
of the issuance of such Guarantee, (ii) was engaged or about to engage in a
business or transaction for which the remaining assets of such Guarantor
constituted unreasonably small capital or (iii) intended to incur, or believed
that it would incur, debts beyond its ability to pay such debts as they matured,
the court could avoid or subordinate such Guarantee in favor of the Guarantor's
other debts or liabilities.  Among other things, a legal challenge of a
Guarantee on fraudulent conveyance grounds may focus on the benefits, if any,
realized by the Guarantor as a result of the issuance by Newpark of the Notes.
To the extent any Guarantee is avoided as a fraudulent conveyance or held
unenforceable for any other reason, holders of the Notes would cease to have any
claim in respect of such Guarantor and would be creditors solely of Newpark and
any Guarantor whose Guarantee was not avoided or held unenforceable.

     Based upon financial and other information currently available to it,
Newpark believes that the Notes and the Guarantees have been and are being
incurred for proper purposes and in good faith and that Newpark and each
Guarantor is solvent and will continue to be solvent after issuing the Notes or
its Guarantee, as the case may be, will have sufficient capital for carrying on
its business after such issuance and will be able to pay its debts as they
mature.  See "Management's Discussion and Analysis of Financial Condition and
Results of Operations," "Description of Certain Other Indebtedness" and
"Description of the Exchange Notes."

IMPACT OF GOVERNMENT REGULATIONS

     Newpark believes that the demand for its principal environmental services
is directly related to regulation of NOW and NORM.  Rescission or relaxation of
such regulations, or a failure of governmental authorities to enforce such
regulations, could result in decreased demand for Newpark's services and,

                                       16
<PAGE>
 
therefore, could materially affect Newpark's consolidated financial statements.
Newpark's business may also be adversely affected by new regulations or changes
in other applicable regulations.

     NOW is currently exempt from the principal Federal statute governing the
handling of hazardous waste. In recent years, proposals have been made to
rescind this exemption. The repeal or modification of the exemption covering NOW
or modification of applicable regulations or their interpretation regarding the
treatment and/or disposal of NOW or NORM waste could require Newpark to alter
significantly its method of doing business. Such repeal or modification could
have a material adverse effect on Newpark's consolidated financial statements.

LOSS OF TECHNOLOGY RIGHTS

     Newpark has been granted U.S. patents on certain aspects of its system for
processing and disposing of NOW and NORM.  There is no assurance that such
patents will give Newpark a meaningful competitive advantage.  In addition, the
environmental services business in the oilfield industry could be impacted by
future technological change and innovation, which could result in a reduction in
the amount of waste being generated or alternative methods of disposal being
developed.

COMPETITION

     The processing of NOW and NORM waste is a relatively new industry.
Competition in this market can be expected to increase as the industry develops.
In the meantime, Newpark expects to encounter significant competition from third
party competitors in connection with any proposed expansion into additional
geographic areas and services.  Barriers to entry by competitors in the
environmental and oilfield services industries are low.  Therefore, competitive
products and services have been and may be successfully developed and marketed
by others.  Newpark also faces competition from oil and gas producing customers
who are continually seeking to enhance and develop their own methods of disposal
instead of utilizing the services of third party NOW and NORM disposal companies
such as Newpark.  The desire to use such internal disposal methods could be
increased by future technological change and innovation and could limit the
ability of Newpark to increase prices.  The increased use by Newpark's oil and
gas producing customers of their own disposal methods and other competitive
factors could have a material adverse effect on Newpark's consolidated financial
statements.  Newpark also faces competition in the drilling fluids market, where
there are several larger companies that may have both lower capital costs and
greater geographic coverage than Newpark, as well as numerous smaller companies
that may have a lower total cost structure.

FAILURE TO COMPLY WITH GOVERNMENTAL REGULATIONS

     Newpark's business is subject to numerous Federal, state and local laws,
regulations and policies that govern environmental protection, zoning and other
matters.  These laws and regulations have changed frequently in the past and it
is reasonable to expect additional changes in the future.  If existing
regulatory requirements change, Newpark may be required to make significant
unanticipated capital and operating expenditures.  Although Newpark believes
that it is presently in material compliance with applicable laws and
regulations, there is no assurance that its operations will continue to comply
with  future laws and regulations.  Governmental authorities may seek to impose
fines and penalties on Newpark or to revoke or deny the issuance or renewal of
operating permits for failure to comply with applicable laws and regulations.
Under such circumstances, Newpark might be required to curtail or cease
operations or conduct site remediation or other corrective action, which could
have a material adverse effect on Newpark's consolidated financial statements.

                                       17
<PAGE>
 
POTENTIAL ENVIRONMENTAL LIABILITY; INSUFFICIENCY OF INSURANCE

     Newpark's business exposes it to the risk of harmful substances escaping
into the environment, resulting in personal injury or loss of life, severe
damage to or destruction of property, environmental damage and suspension of
operations.  The current and past activities of Newpark and the activities of
its former divisions and subsidiaries could result in the imposition of
substantial environmental, regulatory and other liabilities on Newpark,
including the costs of cleanup of contaminated sites and site closure
obligations.  Such liabilities could also be imposed on the basis of negligence,
strict liability, breach of contract with customers or, in many instances, as a
result of contractual indemnification by Newpark of its customers in the normal
course of its business.  Injection wells have been used for many years for
disposal of oilfield waste; however, certain aspects of Newpark's technology
have not been used previously by others and the future performance of such
technology is uncertain.

     While Newpark maintains liability insurance, the insurance is subject to
coverage limits and certain policies exclude coverage for damages resulting from
environmental contamination.  Although there are currently numerous sources from
which such coverage may be obtained, there can be no assurance that insurance
will continue to be available to Newpark on commercially reasonable terms, that
the possible types of liabilities that may be incurred by Newpark will be
covered by its insurance, that Newpark's insurance carriers will be able to meet
their obligations under the policies or that the dollar amount of such
liabilities will not exceed Newpark's policy limits.  Even a partially uninsured
claim, if successful and of significant magnitude, could have a material adverse
effect on Newpark's consolidated financial statements.

RELIANCE ON KEY PERSONNEL

     Newpark is dependent upon the efforts and talents of its executive officers
and certain key personnel.  Loss of the services of one or more of these persons
could adversely affect the operations of Newpark.  None of Newpark's executive
officers is covered by a long-term employment contract.

RESTRICTIONS IMPOSED BY TERMS OF INDEBTEDNESS

     The Indenture governing the terms of the Notes contains certain covenants
limiting, subject to certain exceptions, the incurrence of additional
indebtedness, the payment of dividends, the redemption of capital stock, the
making of certain investments, the issuance of capital stock of subsidiaries,
the creation of liens and other restrictions affecting Newpark's subsidiaries,
the issuance of guarantees, transactions with affiliates, asset sales and
certain mergers and consolidations.  A breach of any of these covenants could
result in an event of default under the Indenture.  In addition, the Credit
Facility contains other restrictive covenants and requires Newpark to satisfy
certain financial tests.  Newpark's ability to comply with such covenants and to
satisfy such financial tests may be affected by events beyond its control.  A
breach of any of these covenants could result in an event of default under the
Credit Facility and the Indenture.  In the event of a default under the Credit
Facility, the lenders thereunder could elect to declare all amounts borrowed,
together with accrued interest, to be immediately due and payable, and the
lenders under the Credit Facility could terminate all commitments thereunder
and, if such borrowed amounts are not paid, enforce their rights pursuant to any
security interests on, or commence litigation that could ultimately result in a
sale of, certain assets of Newpark.  In addition, a default under the Credit
Facility could constitute a cross-default under the Indenture, and a default
under the Indenture could constitute a cross-default under the Credit Facility.
See "Description of Certain Other Indebtedness" and "Description of the Exchange
Notes."

                                       18
<PAGE>
 
POTENTIAL FAILURE TO MAKE PAYMENT UNDER A CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, Newpark will be obligated to
offer to purchase all or a portion of the Notes at 101% of the principal amount
of the Notes, together with accrued and unpaid interest, if any, to the date of
purchase.  If Newpark does not have sufficient funds to repay all of such
indebtedness or is unable to obtain the necessary consents from the holders of
Senior Indebtedness, Newpark may be unable to offer to purchase the Notes, which
will constitute an event of default under the Indenture.  There can be no
assurance that Newpark will have sufficient funds available at the time of any
Change of Control to make any debt payment (including purchases of Notes) as
described above or that Newpark will be able to refinance its outstanding
indebtedness in order to permit it to repurchase the Notes or, if such
refinancing were to occur, that such financing will be on terms favorable to
Newpark.  See "Description of the Exchange Notes--Certain Covenants--Change of
Control."

     The events that constitute a Change of Control under the Indenture may also
be events of default under the Credit Facility or other Senior Indebtedness of
Newpark.  Such events may permit the holders under such debt instruments to
reduce the borrowings thereunder or accelerate the debt and, if the debt is not
paid, to enforce their rights pursuant to security interests on, or commence
litigation that could ultimately result in a sale of, certain assets of Newpark,
thereby limiting Newpark's ability to purchase the Notes.

ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES

     The Exchange Notes are being offered to the Holders of the 144A Notes.  The
144A Notes were offered and sold in December 1997 to "Qualified Institutional
Buyers" (as defined in Rule 144A under the Securities Act) and certain other
qualified buyers and are eligible for trading in the PORTAL market.

     The Exchange Notes will be new securities for which there currently is no
established trading market.  Although Newpark intends to apply for listing of
the Exchange Notes on the NYSE, there can be no assurance that Newpark's
application will be approved or that an active trading market for the Exchange
Notes will develop or continue after the Exchange Offer.  Although the Initial
Purchasers have informed Newpark that they currently intend to make a market in
the Exchange Notes, the Initial Purchasers are not obligated to do so, and any
such market making may be discontinued at any time without notice.  The
liquidity of any market for the Exchange Notes will depend upon the number of
holders of the Exchange Notes, the interest of securities dealers in making a
market in the Exchange Notes and other factors.  Accordingly, there can be no
assurance as to the development or liquidity of any market for the Exchange
Notes.  If an active trading market for the Exchange Notes does not develop, the
market price and liquidity of the Exchange Notes may be adversely affected.  If
the Exchange Notes are traded, they may trade at a discount from the initial
offering price of the 144A Notes for which they were exchanged, depending upon
prevailing interest rates, the market for similar securities, the performance of
Newpark and certain other factors.  The liquidity of, and trading markets for,
the Exchange Notes may also be adversely affected by general declines in the
market for non-investment grade debt.  Such declines may adversely affect the
liquidity of, and trading markets for, the Exchange Notes independent of the
financial performance of or prospects for Newpark.

     Historically, the market for noninvestment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of securities
similar to the Exchange Notes.  There can be no assurance that the market, if
any, for the Exchange Notes will not be subject to similar disruptions.  Any
such disruptions may have an adverse effect on the holders of the Exchange
Notes.

                                       19
<PAGE>
 
     Notwithstanding the registration of the Exchange Notes in the Exchange
Offer, Holders who are "affiliates" (as defined under Rule 405 of the Securities
Act) of the Company may publicly offer for sale or resell the Exchange Notes
only in compliance with the provisions of Rule 144 under the Securities Act. In
addition, Holders who participate in the Exchange Offer should be aware that if
they accept the Exchange Offer for the purpose of engaging in a distribution,
the Exchange Notes received by them may not be publicly reoffered or resold
without complying with the registration and prospectus delivery requirements of
the Securities Act. As a result, each Holder accepting the Exchange Offer will
be required to represent, in connection with its acceptance of the Exchange
Offer, that it acquired the Exchange Notes in the ordinary course of business
and that it is not engaged in, and does not intend to engage in, a distribution
of the Exchange Notes.

EXCHANGE OFFER PROCEDURES

     Issuance of the Exchange Notes for 144A Notes pursuant to the Exchange
Offer will be made only after timely receipt by the Exchange Agent of such 144A
Notes, a properly completed, duly executed Letter of Transmittal (or compliance
with the procedures for book-entry transfer if delivery of 144A Notes is to be
made by book-entry transfer to an account maintained by the Exchange Agent at
the DTC) and all other required documents. Therefore, Holders desiring to tender
their 144A Notes in exchange for Exchange Notes should allow sufficient time to
ensure timely delivery. Newpark is under no duty to give notification of defects
or irregularities with respect to tenders of 144A Notes for exchange. Any 144A
Notes that are not tendered or are tendered but not accepted will, following the
consummation of the Exchange Offer, continue to be subject to the existing
restrictions upon transfer thereof, and, upon consummation of the Exchange
Offer, the registration rights under the Registration Rights Agreement generally
will terminate. In addition, any Holder who tenders pursuant to the Exchange
Offer for the purpose of participating in a distribution of the Exchange Notes
may be deemed to have received restricted securities and, if so, will be
required to comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale. Each broker-dealer that
receives Exchange Notes for its own account in exchange for 144A Notes, where
such 144A Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. See "The
Exchange Offer."

                               THE EXCHANGE OFFER

     The following discussion sets forth or summarizes what Newpark believes are
the material terms of the Exchange Offer, including those set forth in the
Letter of Transmittal distributed with this Prospectus.  This summary is
qualified in its entirety by reference to the full text of the documents
underlying the Exchange Offer, including the Letter of Transmittal and the
Registration Rights Agreement, copies of which are filed as exhibits to the
Registration Statement of which this Prospectus is a part, and are incorporated
by reference herein.

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     In connection with the sale of 144A Notes pursuant to the Purchase
Agreement, dated December 10, 1997 (the "Purchase Agreement"), between Newpark
and the Initial Purchasers, the Initial Purchasers became entitled to the
benefits of the Registration Rights Agreement.

     Under the Registration Rights Agreement, Newpark must use its best efforts
to (i) file a registration statement in connection with a registered exchange
offer of Exchange Notes for 144A Notes within 45 days after December 17, 1997,
the date the 144A Notes were issued (the "Issue Date"), (ii) cause such
registration 

                                       20
<PAGE>
 
statement to become effective under the Securities Act within 105 days of the
Issue Date, (iii) keep such registration statement effective until the closing
of such registered exchange offer and (iv) cause such registered exchange offer
to be consummated within 135 days after the Issue Date. The registered exchange
offer to be made pursuant to the Registration Rights Agreement is intended to
provide each Holder of 144A Notes with the opportunity to exchange any and all
of its 144A Notes for a like principal amount of Exchange Notes , which will be
issued without a restrictive legend and may be reoffered and resold by the
Holder without restrictions or limitations under the Securities Act, subject to
certain limitations. See "--Resale of the Exchange Notes." Subject to limited
exceptions, the Exchange Offer being made hereby, if commenced and consummated
within such applicable time periods, will satisfy the foregoing requirements
under the Registration Rights Agreement. The term "Holder" with respect to the
Exchange Offer means any person in whose name the 144A Notes are registered on
the books of Newpark or any other person who has obtained a properly completed
assignment from the registered holder or any participant in the DTC system whose
name appears on a security position listing as the holder of such 144A Notes and
who desires to deliver such 144A Notes by book-entry transfer through the
facilities of the DTC.

     Upon satisfaction of the foregoing requirements under the Registration
Rights Agreement, Newpark will not be required to pay an increased rate of
interest on the 144A Notes.  Following the consummation of the Exchange Offer,
Holders who did not tender their 144A Notes generally will not have any further
registration rights under the Registration Rights Agreement, and such 144A Notes
will continue to remain subject to certain restrictions on transfer.
Accordingly, the liquidity of the market for such 144A Notes could be adversely
affected.  Holders of 144A Notes seeking liquidity in their investment would
have to rely on exemptions to registration requirements under the securities
laws, including the Securities Act.  Although the 144A Notes have been
designated as eligible for trading in the PORTAL market, because it is expected
that all or substantially all of the Holders of the 144A Notes will elect to
exchange such 144A Notes for Exchange Notes due to the absence of restrictions
on the resale of Exchange Notes under the Securities Act, Newpark anticipates
that the liquidity of the market for any 144A Notes remaining after the
consummation of the Exchange Offer may be substantially limited.

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal, Newpark will accept for exchange
all 144A Notes properly tendered and not withdrawn prior to 5:00 p.m., New York
City time, on the Expiration Date.  Newpark will issue $1,000 principal amount
of Exchange Notes in exchange for each $1,000 principal amount of outstanding
144A Notes accepted in the Exchange Offer.  Holders may tender some or all of
their 144A Notes pursuant to the Exchange Offer in denominations of $1,000 and
integral multiples thereof.

     The form and terms of the Exchange Notes are the same as the form and terms
of the 144A Notes except that (i) the Exchange Notes have been registered under
the Securities Act and hence will not bear legends restricting the transfer
thereof, (ii) the holders of Exchange Notes generally will not be entitled to
certain rights under the Registration Rights Agreement, which rights generally
will terminate as to all of the Notes upon consummation of the Exchange Offer,
and (iii) certain provisions relating to an increase in the stated interest rate
on the 144A Notes provided for under certain circumstances will be eliminated.
The Exchange Notes will evidence the same debt as the 144A Notes and will be
issued under and entitled to the benefits of the Indenture.

     As of the date of this Prospectus, $125,000,000 aggregate principal amount
of the 144A Notes are outstanding.  In connection with the issuance of the 144A
Notes, Newpark arranged for the 144A Notes to 

                                       21
<PAGE>
 
be issued and transferable in book-entry form through the facilities of the DTC,
acting as depositary. The Exchange Notes will also be issuable and transferable
in book-entry form through the DTC.

     This Prospectus, together with the accompanying Letter of Transmittal, is
initially being sent to all registered Holders of the 144A Notes as of the close
of business on                  , 1998.  The Exchange Offer is not conditioned
upon any minimum aggregate principal amount of 144A Notes being tendered, and
Holders of the 144A Notes do not have any appraisal or dissenters' rights in
connection with the Exchange Offer.

     Newpark shall be deemed to have accepted validly tendered 144A Notes when,
as and if Newpark has given oral or written notice thereof to the Exchange
Agent.  The Exchange Agent will act as agent for the tendering Holders of 144A
Notes for the purposes of receiving the Exchange Notes from Newpark and
delivering Exchange Notes to such Holders.  Newpark's obligation to accept 144A
Notes for exchange pursuant to the Exchange Offer is subject to certain
customary conditions as set forth under "--Conditions."

     If any tendered 144A Notes are not accepted for exchange because of an
invalid tender or the occurrence of certain other events set forth herein,
certificates for any such unaccepted 144A Notes will be returned, without
expense, to the tendering Holder thereof as promptly as practicable after the
Expiration Date.

     Holders of 144A Notes who tender pursuant to the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the Letter of Transmittal, transfer taxes with respect to the exchange of 144A
Notes pursuant to the Exchange Offer.  Newpark will pay all charges and
expenses, other than certain applicable taxes, in connection with the Exchange
Offer. See "--Solicitation of Tenders; Fees and Expenses."

     NEITHER THE BOARD OF DIRECTORS OF NEWPARK NOR NEWPARK MAKES ANY
RECOMMENDATION TO HOLDERS OF 144A NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM
TENDERING ALL OR ANY PORTION OF THEIR 144A NOTES PURSUANT TO THE EXCHANGE OFFER.
MOREOVER, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION.  HOLDERS
OF 144A NOTES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE
EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF 144A NOTES TO TENDER, AFTER
READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISORS, IF ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

     The Exchange Offer will remain open for acceptance for a period of not
less than 30 days after notice is mailed to Holders.  The Expiration Date will
be 5:00 p.m., New York City time, on          , 1998, unless Newpark, in its
sole discretion, extends the Exchange Offer, in which case the Expiration Date
will be the latest business day to which the Exchange Offer is extended.  In
order to extend the Expiration Date, Newpark will notify the Exchange Agent of
any extension by oral or written notice and will mail to the record Holders an
announcement thereof, each prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date.  During any such
extension, all 144A Notes previously tendered and not withdrawn as herein
provided will remain subject to the Exchange Offer and may be accepted for
exchange by Newpark.

                                       22
<PAGE>
 
     Newpark reserves the right (i) to delay accepting any 144A Notes, to extend
the Exchange Offer or to terminate the Exchange Offer and not accept 144A Notes
not previously accepted if any of the conditions set forth under "--Conditions"
shall have occurred and shall not have been waived by Newpark, by giving oral or
written notice of such delay, extension or termination to the Exchange Agent, or
(ii) to amend the terms of the Exchange Offer in any manner.  Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof.  If the Exchange Offer is amended
in a manner determined by Newpark to constitute a material change, Newpark will
promptly disclose such amendment in a manner reasonably calculated to inform the
Holders of such amendment, and Newpark will extend the Exchange Offer for a
period of five to ten business days, depending upon the significance of the
amendment and the manner of disclosure to Holders, if the Exchange Offer would
otherwise expire during such five to ten business day period.

     Without limiting the manner in which Newpark may choose to make public
announcement of any extension, amendment or termination of the Exchange Offer,
Newpark shall have no obligation to publish, advertise or otherwise communicate
any such public announcement, other than by making a timely release to the Dow
Jones News Service.

INTEREST ON THE EXCHANGE NOTES

     Interest on the Notes is payable semi-annually on June 15 and
December 15 of each year at the rate of 8 5/8% per annum. The Exchange Notes
will bear interest from the Issue Date or the most recent interest payment date
to which interest on the 144A Notes has been paid, whichever is later.
Accordingly, Holders of 144A Notes that are accepted for exchange will not
receive interest that is accrued but unpaid on the 144A Notes at the time of
tender, but such interest will be payable in respect of the Exchange Notes
delivered in exchange for such 144A Notes on the first interest payment date
after the Expiration Date. Each 144A Note accepted for exchange will cease to
bear interest from and after the date of consummation of the Exchange Offer.

PROCEDURES FOR TENDERING

     Only a Holder of 144A Notes may tender such 144A Notes pursuant to the
Exchange Offer. To tender pursuant to the Exchange Offer, a Holder must
complete, sign and date the Letter of Transmittal, or a facsimile thereof, in
accordance with the instructions contained herein and therein, have the
signatures thereon guaranteed if required by Instruction 5 of the Letter of
Transmittal, and deliver such Letter of Transmittal or such facsimile, together
with the 144A Notes and any other required documents, to the Exchange Agent
prior to 5:00 p.m., New York City time, on the Expiration Date (or comply with
the procedures for book-entry transfer described below if delivery of 144A Notes
is to be made by book-entry transfer to an account maintained by the Exchange
Agent at the DTC). Confirmation of such book-entry transfer must be received by
the Exchange Agent prior to the Expiration Date.

     The tender by a Holder of 144A Notes and the acceptance thereof by Newpark
will constitute an agreement between such Holder and Newpark in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.  If less than all of the 144A Notes delivered to the Exchange Agent
are tendered, a tendering Holder should fill in the amount of 144A Notes being
tendered in the appropriate box on the Letter of Transmittal.  The entire amount
of 144A Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

THE METHOD OF DELIVERY OF 144A NOTES AND THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION 

                                       23
<PAGE>
 
AND RISK OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT
HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR 144A NOTES SHOULD BE SENT TO
NEWPARK. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT SUCH TENDER FOR SUCH HOLDERS.

     Any beneficial Holder whose 144A Notes are registered in the name of such
Holder's broker, dealer, commercial bank, trust company or other nominee and who
wishes to tender should contact such registered Holder promptly and instruct
such registered Holder to tender on its behalf. If such beneficial Holder wishes
to tender on such beneficial Holder's own behalf, such beneficial Holder must,
prior to completing and executing the Letter of Transmittal and delivering its
144A Notes, either make appropriate arrangements to register ownership of the
144A Notes in such Holder's name or obtain a properly completed assignment from
the registered Holder. The transfer of record ownership may take considerable
time, and completion of such transfer prior to the Expiration Date may not be
possible.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a member firm of the Securities Transfer
Agents Medallion Program, the New York Stock Exchange Medallion Signature
Program or the Stock Exchange Medallion Program (an "Eligible Institution")
unless the 144A Notes tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. If the Letter of Transmittal is
signed by a person other than the registered Holder of any 144A Notes listed
therein, such 144A Notes must be endorsed or accompanied by appropriate
assignments which authorizes such person to tender the 144A Notes on behalf of
the registered Holder, in each case signed as the name of the registered Holder
or Holders appears on the 144A Notes with the signature thereon guaranteed by an
Eligible Institution. If the Letter of Transmittal or any 144A Notes or
assignments are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and,
unless waived by Newpark, evidence satisfactory to Newpark of their authority to
so act must be submitted with the Letter of Transmittal.

     Newpark understands that the Exchange Agent will make a request promptly
after the date of this Prospectus to establish an account with respect to the
144A Notes at the DTC for the purpose of facilitating the Exchange Offer unless
the Exchange Agent already has established an account with the DTC suitable for
the Exchange Offer, and, subject to the establishment thereof, any financial
institution that is a participant in the DTC may make book-entry delivery of the
144A Notes by causing the DTC to transfer such 144A Notes into the Exchange
Agent's account with respect to the 144A Notes in accordance with the DTC's
procedures for such transfer. Although delivery of 144A Notes may be effected
through book-entry transfer into the Exchange Agent's account at the DTC, the
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received by the Exchange Agent at its address set forth herein under "--
Exchange Agent" prior to 5:00 p.m., New York City time, on the Expiration Date.
DELIVERY OF DOCUMENTS TO THE DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE
AGENT.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered 144A Notes and withdrawal of tendered 144A
Notes will be determined by Newpark in its sole discretion, which determination
will be final and binding. Newpark reserves the absolute right to reject any and
all 144A Notes not properly tendered or any 144A Notes Newpark's acceptance of
which would, in the

                                       24
<PAGE>
 
opinion of counsel for Newpark, be unlawful. Newpark also reserves the right to
waive any irregularities or conditions of tender as to particular 144A Notes.
Newpark's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of 144A Notes must be cured within such time as Newpark
shall determine. Neither Newpark, the Exchange Agent nor any other person shall
be under any duty to give notification of defects or irregularities with respect
to tenders of 144A Notes, nor shall any of them incur any liability for failure
to give such notification. Tenders of 144A Notes will not be deemed to have been
made until such irregularities have been cured or waived. Any 144A Notes
received by the Exchange Agent that are not properly tendered or the tender of
which is otherwise rejected by the Company and as to which the defects or
irregularities have not been cured or waived will be returned without cost to
such Holder by the Exchange Agent to the tendering Holder thereof (or, in the
case of 144A Notes tendered by book-entry transfer into the Exchange Agent's
account at the DTC pursuant to the book-entry procedures described above, such
non-exchanged 144A Notes will be credited to an account maintained with the
DTC), unless otherwise provided in the Letter of Transmittal, as soon as
practicable following the Expiration Date.

     The Letter of Transmittal will include representations to Newpark with
respect to certain securities law matters.  See "--Resale of the Exchange
Notes."

GUARANTEED DELIVERY PROCEDURES

     Holders who wish to tender their 144A Notes and (i) whose 144A Notes are
not immediately available, or (ii) who cannot deliver their 144A Notes, the
Letter of Transmittal or any other required documents to the Exchange Agent (or
comply with the procedures for book-entry transfer) prior to the Expiration
Date, may effect a tender if:

     (a)  the tender is made through an Eligible Institution;

     (b)  prior to the Expiration Date, the Exchange Agent receives from such
          Eligible Institution a properly completed and duly executed Notice of
          Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
          setting forth the name and address of the Holder of the 144A Notes,
          the certificate or registration number or numbers of such 144A Notes
          and the principal amount of 144A Notes tendered, stating that the
          tender is being made thereby, and guaranteeing that, within three NYSE
          trading days after the execution of the Notice of Guaranteed Delivery,
          the Letter of Transmittal (or facsimile thereof), together with the
          certificate(s) representing the 144A Notes to be tendered in proper
          form for transfer (or a confirmation of book-entry transfer of such
          144A Notes into the Exchange Agent's account at the DTC) and any other
          documents required by the Letter of Transmittal, will be deposited by
          the Eligible Institution with the Exchange Agent; and

     (c)  such properly completed and executed Letter of Transmittal (or
          facsimile thereof), together with the certificate(s) representing all
          tendered 144A Notes in proper form for transfer (or a confirmation of
          book-entry transfer of such 144A Notes into the Exchange Agent's
          account at the DTC) and all other documents required by the Letter of
          Transmittal, are received by the Exchange Agent within three NYSE
          trading days after the execution of the Notice of Guaranteed Delivery.

     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their 144A Notes according to the guaranteed
delivery procedures set forth above.

                                       25
<PAGE>
 
WITHDRAWAL OF TENDERS

     Except as otherwise provided herein, tenders of 144A Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

     To withdraw a tender of 144A Notes pursuant to the Exchange Offer, a
written or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at the address set forth herein prior to 5:00 p.m., New York City
time, on the Expiration Date. Any such notice of withdrawal must (i) specify the
name of the person having deposited the 144A Notes to be withdrawn (the
"Depositor"), (ii) identify the 144A Notes to be withdrawn (including the
certificate or registration number(s) and principal amount of such 144A Notes,
or, in the case of notes tendered by book-entry transfer, the name and number of
the account at the DTC to be credited), (iii) be signed by the Depositor in the
same manner as the original signature on the Letter of Transmittal by which such
144A Notes were tendered (including any required signature guarantees) or be
accompanied by documents of transfer sufficient to have the Trustee with respect
to the 144A Notes register the transfer of such 144A Notes into the name of the
person withdrawing the tender, (iv) specify the name in which any such 144A
Notes are to be registered, if different from that of the Depositor and (v)
include a statement that such Holder is withdrawing such Holder's election to
have such 144A Notes exchanged. All questions as to the validity, form and
eligibility (including time of receipt) of such withdrawal notices will be
determined by Newpark, whose determination will be final and binding on all
parties. Any 144A Notes so withdrawn will be deemed not to have been validly
tendered for purposes of the Exchange Offer, and no Exchange Notes will be
issued with respect thereto unless the 144A Notes so withdrawn are validly
retendered. Any 144A Notes which have been tendered but which are not accepted
for exchange will be returned to the Holder thereof without cost to such Holder
as soon as practicable after withdrawal, rejection of tender or termination of
the Exchange Offer. Properly withdrawn 144A Notes may be retendered by following
one of the procedures described under "--Procedures for Tendering" at any time
prior to the Expiration Date.

CONDITIONS

     Notwithstanding any other term of the Exchange Offer, Newpark shall not be
required to accept for exchange, or to exchange Exchange Notes for, any 144A
Notes, and may terminate or amend the Exchange Offer as provided herein before
the acceptance of such 144A Notes, if:

     (a)  any action or proceeding is instituted or threatened in any court or
          by or before any governmental agency or regulatory authority or any
          injunction, order or decree is issued with respect to the Exchange
          Offer which, in the sole judgment of Newpark, might impair the ability
          of Newpark to proceed with the Exchange Offer; or

     (b)  any law, statute, rule, regulation or interpretation by the staff of
          the Commission is proposed, adopted or enacted, which, in the
          reasonable judgment of Newpark, might materially impair the ability of
          Newpark to proceed with the Exchange Offer; or

     (c)  any governmental approval has not been obtained, which approval
          Newpark, in its sole discretion, deems necessary for the consummation
          of the Exchange Offer; or

     (d)  there shall have been proposed, adopted or enacted any law, statute,
          rule or regulation (or an amendment to any existing law, statute, rule
          or regulation) which, in the sole judgment of Newpark, might
          materially impair the ability of Newpark to proceed with the Exchange
          Offer.

                                       26
<PAGE>
 
     If Newpark determines in its reasonable judgment that any of the conditions
set forth above are not satisfied, Newpark may (i) terminate the Exchange Offer
and refuse to accept any 144A Notes and return all tendered 144A Notes to the
tendering Holders, (ii) extend the Exchange Offer and retain all 144A Notes
tendered prior to the expiration of the Exchange Offer subject, however, to the
rights of Holders to withdraw such 144A Notes (see "--Withdrawals of Tenders")
or (iii) waive such unsatisfied conditions with respect to the Exchange Offer
and accept all properly tendered 144A Notes which have not been withdrawn.
Moreover, regardless of whether any of such conditions has occurred, Newpark may
amend the Exchange Offer in any manner which, in its good faith judgment, is
advantageous to Holders of the 144A Notes.

     The foregoing conditions are for the sole benefit of Newpark and may be
asserted by Newpark regardless of the circumstances giving rise to any such
condition or may be waived by Newpark in whole or in part at any time and from
time to time in its sole discretion. The failure by Newpark at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right, and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time. If a waiver constitutes a material
change in the Exchange Offer, Newpark will disclose such change by means of a
supplement to this Prospectus that will be distributed to each registered
Holder, and Newpark will extend the Exchange Offer for a period of five to ten
business days, depending upon the significance of the waiver and the manner of
disclosure to the registered Holders, if the Exchange Offer would otherwise
expire during such period. Any determination by Newpark concerning the events
described above will be final and binding upon all parties.

     In addition, Newpark will not accept for exchange any 144A Notes tendered,
and no Exchange Notes will be issued in exchange for any such 144A Notes, if at
such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus is a part or the Indenture is
not qualified under the Trust Indenture Act of 1939, as amended.  Newpark is
required to use every reasonable effort to obtain the withdrawal of any such
stop order at the earliest possible time.

     The Exchange Offer is not conditioned upon any minimum principal amount of
144A Notes being tendered for exchange.

EXCHANGE AGENT

     State Street Bank and Trust Company, the Trustee under the Indenture, has
been appointed as Exchange Agent for the Exchange Offer.  In such capacity, the
Exchange Agent has no fiduciary duties and will be acting solely on the basis of
directions of Newpark.  All executed Letters of Transmittal must be directed to
the Exchange Agent at the applicable address set forth below.  Questions and
requests for assistance and requests for additional copies of this Prospectus or
of the Letter of Transmittal should be directed to the Exchange Agent addressed

        DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OR FACSIMILE NUMBER
OTHER THAN SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

SOLICITATION OF TENDERS; FEES AND EXPENSES

     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by Newpark. The principal solicitation for tenders pursuant to the
Exchange Offer is being made by mail; however, additional solicitations may be
made by telegraph, facsimile, telephone or in person by officers and regular
employees of Newpark and its affiliates.

     Newpark has not retained any dealer-manager in connection with the Exchange
Offer and will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. Newpark will, however, pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
the Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith and pay other registration expenses, including fees and expenses of
the Trustee, filing fees, blue sky fees, accounting and legal fees and printing
and distribution expenses. Newpark may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, Letters of Transmittal
and related documents to the beneficial owners of the 144A Notes and in handling
or forwarding tenders for exchange.

     Newpark will pay all transfer taxes, if any, applicable to the exchange of
144A Notes pursuant to the Exchange Offer.  If, however, certificates
representing Exchange Notes or 144A Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered Holder of the 144A Notes
tendered, or if tendered 144A Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of 144A Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered Holder or any other persons) will be payable by the tendering
Holder.  If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering Holder.

ACCOUNTING TREATMENT

     The Exchange Notes will be recorded at the same carrying value as the 144A
Notes for which they are exchanged, which is the aggregate principal amount of
the 144A Notes, as reflected in Newpark's accounting records on the date of
exchange.  Accordingly, no gain or loss for accounting purposes will be
recognized in connection with the Exchange Offer.  The cost of the Exchange
Offer will be deferred and amortized over the term of the Exchange Notes.

RESALE OF THE EXCHANGE NOTES

     Newpark is making the Exchange Offer in reliance on interpretations of the
staff of the Commission as set forth in certain no-action letters addressed to
third parties in other transactions.  However, Newpark has not sought its own
no-action letter, and there can be no assurance that the staff of the Commission
would take a similar position with respect to the Exchange Offer.  Based on
these interpretations by the staff of the Commission, Newpark believes that
Exchange Notes issued pursuant to the Exchange Offer in exchange for 144A Notes
may be offered for resale, resold and otherwise transferred by a Holder thereof
(other than any such Holder which is an "affiliate" of Newpark within the
meaning of Rule 405 of the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided

                                       28
<PAGE>
 
that the Holder is acquiring the Exchange Notes in the ordinary course of its
business, and such Holder does not intend to participate, and has no arrangement
or understanding to participate, in the distribution of such Exchange Notes.
Any Holder that is an affiliate of Newpark or that tenders pursuant to the
Exchange Offer with the intention to participate, or for the purpose of
participating, in a distribution of the Exchange Notes may not rely on the
position of the staff of the Commission set forth in the above-referenced no-
action letters, but instead must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.

     Each broker-dealer that receives Exchange Notes for its own account in
exchange for 144A Notes that were acquired by such broker-dealer as a result of
market-making activities or other trading activities may be a statutory
underwriter and must acknowledge, in the Letter of Transmittal, that it will
deliver a prospectus in connection with any resale of such Exchange Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for 144A Notes
where such 144A Notes were acquired by such broker-dealer as a result of market-
making activities or other trading activities. Newpark has agreed that, for a
period of 180 days after the Expiration Date, it will make this Prospectus
available to broker-dealers for use in connection with any such resales. A
broker-dealer which delivers such a prospectus to purchasers in connection with
such resales will be subject to certain of the civil liability provisions under
the Securities Act and will be bound by certain provisions of the Registration
Rights Agreement (including certain indemnification rights and obligations).

     The Letter of Transmittal includes representations to Newpark that, among
other things, (i) the Exchange Notes to be acquired pursuant to the Exchange
Offer are being acquired in the ordinary course business of the person receiving
such Exchange Notes (whether or not such person is the Holder), (ii) neither the
Holder nor any such other person is engaged in, intends to engage in or has any
arrangement or understanding with any person to participate in the distribution
of such Exchange Notes, (iii) neither the Holder nor any such other person is an
"affiliate" (as defined in Rule 405 of the Securities Act) of Newpark and (iv)
if the tendering Holder is a broker or dealer (as defined in the Exchange Act)
(a) it acquired the 144A Notes for its own account as a result of market-making
activities or other trading activities and (b) it has not entered into any
arrangement or understanding with the Company or any "affiliate" thereof (within
the meaning of Rule 405 of the Securities Act) to distribute the Exchange Notes
to be received in the Exchange Offer. A breach of any of the foregoing
representations could result in the Holder incurring liability under the
Securities Act for which it is not indemnified by Newpark.

     Newpark has agreed, pursuant to the Registration Rights Agreement and
subject to certain specified limitations therein, to register or qualify the
Exchange Notes for offer or sale under the securities or blue sky laws of such
jurisdictions as any Holder of the Exchange Notes reasonably requests in
writing.  Such registration or qualification may require the imposition of
restrictions or conditions (including suitability requirements for offerees or
purchasers) in connection with the offer or sale of any Exchange Notes.  Unless
a Holder so requests, Newpark does not currently intend to register or qualify
the sale of the Exchange Notes in any such jurisdictions.

                                       29
<PAGE>
 
     If any changes in law or the applicable interpretations of the staff of the
Commission do not permit the Issuers to effect the Exchange Offer, or if for any
other reason the Exchange Offer is not consummated within 135 days of the date
of original issuance of the 144A Notes, or if a Holder of the 144A Notes is not
permitted by applicable law to participate in the Exchange Offer or elects to
participate in the Exchange Offer but does not receive fully tradeable Exchange
Notes pursuant to the Exchange Offer, the Issuers will, in lieu of effecting the
registration of the Exchange Notes as contemplated herein and at the Issuers'
cost, (i) as promptly as practicable, file with the Commission a shelf
registration statement (the "Shelf Registration Statement") covering resales of
the 144A Notes, (ii) use their best efforts to cause the Shelf Registration
Statement to be declared effective under the Securities Act by the 135th day
after the date of original issuance of the 144A Notes and (iii) use their best
efforts to keep the Shelf Registration Statement effective for a period of two
years after its effective date (or for such shorter period that will terminate
when all of the 144A Notes covered by the Shelf Registration Statement have been
sold pursuant thereto or cease to be outstanding).

     Information set forth above concerning certain interpretations of and
positions taken by the staff of the Commission is not intended to constitute
legal advice and prospective investors should consult their own legal advisors
with respect to such matters.

CONSEQUENCES OF FAILURE TO EXCHANGE

     As a result of the making of, and upon acceptance for exchange of all
validly tendered 144A Notes pursuant to the terms of, the Exchange Offer,
Newpark will have fulfilled one of its obligations under the Registration Rights
Agreement, and Holders of 144A Notes who do not tender their 144A Notes
generally will not have any further registration rights under the Registration
Rights Agreement or otherwise.  Accordingly, any Holder that does not exchange
such Holder's 144A Notes for Exchange Notes will continue to hold the untendered
144A Notes and will be entitled to all the rights and will be subject to all the
limitations applicable thereto under the Indenture, except to the extent that
such rights or limitations, by their terms, terminate or cease to have further
effectiveness as a result of the Exchange Offer.

     The 144A Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will remain restricted securities and will continue to be subject
to the restrictions on transfer set forth in the legend thereon and in the
Indenture. Accordingly, such 144A Notes may be offered, resold or otherwise
transferred only (i) to Newpark (upon redemption thereof or otherwise), (ii)
pursuant to an effective registration statement under the Securities Act, (iii)
so long as the 144A Notes are eligible for resale pursuant to Rule 144A under
the Securities Act, to a Qualified Institutional Buyer in a transaction meeting
the requirements of Rule 144A, (iv) outside the United States to a foreign
person pursuant to the exemption from the registration requirements of the
Securities Act provided by Regulation S thereunder, (v) pursuant to an exemption
from registration under the Securities Act provided by Rule 144 thereunder (if
available), or (vi) to an accredited investor as such term is defined under Rule
501 of the Securities Act in a transaction exempt from the registration
requirements of the Securities Act, in each case in accordance with any
applicable securities laws of any state of the United States or other applicable
jurisdiction. See "Risk Factors--Restrictions on Transfer."

     To the extent that 144A Notes are tendered and accepted in the Exchange
Offer, the liquidity of the trading market for untendered 144A Notes could be
adversely affected.

                                       30

OTHER

     Participation in the Exchange Offer is voluntary, and Holders should
carefully consider whether to accept.  Holders are urged to consult their
financial and tax advisors in making their decision on what action to take.

     Newpark may in the future seek to acquire untendered 144A Notes, to the
extent permitted by applicable law, in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise.  Newpark has no
present plans to acquire any 144A Notes that are not tendered in the Exchange
Offer or to file a registration statement to permit resales of any untendered
144A Notes.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OFFER

     The following discussion is based upon current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), existing and proposed Treasury
Department regulations and existing administrative interpretations and court
decisions. There can be no assurance that the Internal Revenue Service (the
"IRS") will not take a contrary view, and no ruling from the IRS has been or
will be sought. Legislative, judicial or administrative changes or
interpretations may be forthcoming that could alter or modify the statements and
conditions set forth herein. Any such changes or interpretations may or may not
be retroactive and could affect the tax consequences to Holders. Certain Holders
of the 144A Notes (including insurance companies, tax-exempt organizations,
financial institutions, broker-dealers, foreign corporations and persons who are
not citizens or residents of the United States) may be subject to special rules
not discussed below. EACH HOLDER OF A 144A NOTE SHOULD CONSULT ITS OWN TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF EXCHANGING SUCH HOLDER'S 144A
NOTES FOR EXCHANGE NOTES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE,
LOCAL OR FOREIGN TAX LAWS.

     The issuance of the Exchange Notes to Holders of the 144A Notes pursuant to
the terms set forth in this Prospectus should not constitute an exchange for
United States federal income tax purposes because such exchange does not
represent a significant modification of the debt instruments.  Consequently, no
gain or loss should be recognized by Holders of the 144A Notes upon receipt of
the Exchange Notes, and ownership of the Exchange Notes should be considered a
continuation of ownership of the 144A Notes.  For purposes of determining gain
or loss upon the subsequent sale or exchange of the Exchange Notes, a Holder's
basis in the Exchange Notes should be the same as such Holder's basis in the
144A Notes exchanged therefor.  A Holder's holding period for the Exchange Notes
should include the Holder's holding period for the 144A Notes exchanged
therefor.

     See also "Description of Certain Federal Income Tax Consequences of an
Investment in the Exchange Notes."

                                USE OF PROCEEDS

     Newpark will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby.  In consideration for issuing the Exchange Notes
as contemplated by this Prospectus, Newpark will receive in exchange a like
principal amount of 144A Notes, the terms of which are identical in all material
respects to the Exchange Notes.  The 144A Notes surrendered in exchange for the
Exchange Notes will be retired and canceled and cannot be reissued.
Accordingly, issuance of the Exchange Notes will not result in any change in the
capitalization of Newpark.

     The net proceeds to Newpark from the 144A Notes Offering were approximately
$121.5 million.  Newpark used the net proceeds from the 144A Notes Offering as
follows: (i) approximately $90.5 million was used to repay all the borrowings
then outstanding under the Credit Facility, (ii) approximately $17 million has
been or will be used to fund capital expenditures and (iii) the balance,
consisting of approximately $14 million, will be used for general corporate
purposes, including working capital.  Pending such use, Newpark invested the
balance of the net proceeds in short-term investments.  See "Description of
Certain Other Indebtedness" for further information regarding the Credit
Facility.

     Although Newpark fully repaid its outstanding borrowings under the Credit
Facility, it may borrow amounts thereunder from time to time in the future for
general corporate purposes.  As of September 30, 1997, on an as adjusted basis
after giving effect to the 144A Notes Offering and the application of the net
proceeds therefrom, Newpark would have had an aggregate of $88.0 million of
available borrowings under the Credit Facility.  See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."

     The following table sets forth the consolidated capitalization of Newpark
as of September 30, 1997, and on an as adjusted basis to give effect to the 144A

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion of Newpark's financial condition, results of
operations, liquidity and capital resources should be read in conjunction with
the Consolidated Financial Statements and the notes thereto included and
incorporated by reference herein.

OVERVIEW

     The Baker Hughes Rotary Rig Count has historically been viewed as the most
significant single indicator of oil and gas drilling activity in the domestic
market.  In 1993, the United States rig count averaged 754 rigs in operation,
and increased to 774 in 1994.  In 1995, the rig count averaged 723, the second
lowest on record since the advent of the indicator in the 1940's, and in 1996,
the rig count increased slightly to an average of 779.  For the nine months
ended September 30, 1997, the rig count continued to increase to an average of
925.

     Newpark's primary market area includes the following rig count measurement
areas: (i) South Louisiana Land; (ii) Texas Railroad Commission Districts 2 and
3; (iii) Louisiana and Texas Inland Waters; and (iv) the Offshore Gulf of
Mexico.  The rig count trend in Newpark's primary markets have tracked these
national trends as set forth in the table below:

     Newpark believes the decline in the rig count within Newpark's market
during 1995, which continued in the first quarter of 1996, was primarily the
result of low natural gas prices during most of 1995.  The decline in the rig
count created downward price pressure on Newpark's site preparation and mat
rerental businesses.  Prices were also negatively impacted by a significant
shift in land drilling activity towards the Austin Chalk area, which is further
inland and less frequently requires the use of  Newpark's mat systems at the
drilling locations.  During the fourth quarter of 1996, the downward price
pressure began to alleviate, as shortages of equipment and supporting services
in the land market began to appear as a result of increased drilling activity.
In addition, Newpark was able to modify a portion of its mat rental fleet, which
allowed Newpark to compete with native rock foundations typically used in inland
areas such as the Austin Chalk.  As of the week ended January 16, 1998 the U.S.
rig count was 989, with 259 rigs within Newpark's market.

RECENT ACQUISITIONS

     In February 1997, Newpark acquired SBM, a full-service drilling fluids
company, which serves customers in the Louisiana and Texas Gulf Coast, in
exchange for an aggregate of 2,328,000 shares of Newpark common stock.  The
acquisition was accounted for as a pooling-of-interests, with direct acquisition
costs of $316,000 charged to current operations.  SBM has since changed its name
to Newpark Drilling Fluids, Inc.  Since the SBM acquisition, Newpark has
completed six additional acquisitions in the drilling fluids industry, in
exchange for an aggregate of 1,371,112 shares of Newpark common stock.  The
acquisitions involved four drilling fluids distribution companies, one specialty
chemical company and one specialty milling company.  To expand its presence and
service capabilities in the site preparation business, 

                                       34

Newpark has recently acquired two oilfield site contractors in exchange for an
aggregate of 990,888 shares of Newpark common stock. Newpark also has recently
acquired additional properties and facilities to expand its disposal capacity,
including two active injection wells on 37 acres of land adjacent to Newpark's
Big Hill facility, four facilities in the Permian Basin at which brine is
extracted and sold and NOW is disposed in the salt domes or caverns created by
the extraction process, and 120 acres of land adjacent to its Big Hill facility,
which Newpark plans to develop into an industrial waste disposal facility.

</TABLE>

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1996

Revenues

     Total revenues increased to $148.8 million in the 1997 period, from $90.6
million in the 1996 period, an increase of $58.2 million, or 64.1%.  The
increase consisted primarily of a $42.9 million increase in fluids management
services revenue and a $17.0 million increase in mat rental revenue.  Principal
components of the increase in fluids management services revenue were drilling
fluids sales and service revenue, which increased $25.5 million, and waste
disposal revenue, which increased $16.4 million.  Drilling fluids sales
increased as a result of a series of acquisitions made during 1997 in the
drilling fluids market, the expansion of the businesses acquired through
increased inventories and facilities to service new and expanded markets and an
increase in drilling activity.  The increase in waste disposal revenues can be
primarily ascribed to the acquisition of a competitor's marine-related
collection operations in August 1996 and increases in the domestic market rig
count.  NOW revenues for 1997 increased to $42.2 million, compared to $22.1
million in 1996.  The volume of NOW received increased to 4.1 million barrels,
from 2.4 million barrels.  NORM revenue was $3.1 million in 1997, compared to
$6.9 million in 1996, due to decreased site remediation 

                                       35
<PAGE>
 
activity. The increase in mat rental revenue reflects two acquisitions,
improvements in the domestic market rig count and increased pricing for
Newpark's mat inventory.

Restructure Expense

     During the nine months ended September 30, 1996, Newpark recorded a non-
recurring restructure charge in the amount of $2.4 million.  A total of
approximately $1.8 million was related to the restructuring of certain of
Newpark's NOW processing operations and staffing changes to facilitate the
integration of its operations with those acquired from a competitor.  Newpark
recognized an additional $600,000 of non-recurring costs associated with the
termination of processing operations at its original NORM facility at Port
Arthur, Texas and the partial closure of the site.

Operating Income

     Operating income of $42.8 million in the 1997 period increased $22.5
million, or 110.9%, compared to $20.3 million in the 1996 period.  Factors
contributing to the increase included increased profitability from disposal
operations, increased utilization and higher pricing for Newpark's mat inventory
and increased profitability from drilling fluids sales.

Provision for Income Taxes

     For the 1997 and 1996 periods, Newpark recorded income tax provisions of
$14.7 million and $6.2 million, equal to 36.6% and 35.5% of pre-tax income,
respectively.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

Revenues

     Total revenues increased to $136.0 million in 1996, from $105.7 million in
1995, an increase of $30.3 million or 28.7%.  In the fluid management services
area, revenues increased $20.5 million, as NOW revenue increased $11.1 million,
NORM revenue increased $2.7 million and product sales and engineering revenue
increased $6.7 million.  The volume of NOW waste processed increased by 1.1
million barrels, or 36%, to 4.0 million barrels, from 2.9 million in 1995.  In
addition to increased volume, Newpark benefitted from increased NOW prices.  The
volume of NORM waste processed grew to 143,500 barrels, from 70,000 barrels in
1995, while pricing declined due to increased volume of lower priced remediation
projects made possible by the new direct injection license.  In the mat service
area, revenue grew by $2.0 million, or 6.4%, due primarily to sales of mats for
nonoilfield applications.  Revenues in the integrated services area increased
$8.0 million due to increased onsite environmental management and other services
incidental to site preparation activities, coupled with increased wood product
sales.

Operating Income

     Operating income increased by $10.5 million, or 48.6%, to $32.0 million in
1996, compared to $21.5 million in 1995.  Operating margin improved to 23.5% in
1996, as compared to 20.4% in 1995.  The increase resulted primarily from
increased profitability from NOW and NORM disposal operations.

     General and administrative expenses decreased as a proportion of revenue to
2.1% in 1996, from 2.5% in 1995, and increased in absolute amount by $262,000.

                                       36
<PAGE>
 
     During 1996, Newpark recorded a restructure charge in the amount of $2.4
million.  Approximately $1.8 million of this amount was related to the
restructuring of certain of Newpark's NOW processing operations and staffing
changes to facilitate the integration of its operations with those recently
acquired from a competitor. Newpark recognized an additional $600,000 of non-
recurring costs associated with the termination of processing operations at its
original NORM facility at Port Arthur, Texas, and the partial closure of the
site.

Interest Expense

     Interest expense was substantially unchanged at $3.9 million in 1996,
compared to $3.8 million in 1995.

Provision for Income Taxes

     For 1996 and 1995, Newpark recorded income tax provisions of $9.8 million
and $5.0 million, for effective tax rates of 34.7% and 28.3%, respectively.  The
1995 provision reflects the benefit realized from federal tax carryforwards
which were fully recognized in 1995.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994

Revenues

     Total revenues increased to $105.7 million in 1995, from $86.6 million in
1994, an increase of $19.1 million or 22.0%. The components of the increase by
product line are as follows:  (i) fluids management services revenues increased
$11.1 million, as NOW revenue increased $5.5 million (due almost exclusively to
additional volume), NORM processing revenue increased to $6.0 million on
approximately 70,000 barrels in the full year 1995, from $1.2 million in revenue
and 15,000 barrels in the two months of operations during 1994, and product
sales and engineering revenue increased $800,000; (ii) mat revenue increased
$7.7 million, or 34%, due to (a) increased volume installed at similar pricing
compared to the prior year and (b) an increase in revenues from extended
rerentals of $3.6 million resulting from the longer use of sites, as the size of
the average location installed in 1995 grew 17% from the prior year, primarily
the result of the trend toward deeper drilling in more remote locations,
requiring larger sites to accommodate increased equipment and supplies on the
site; and (iii) integrated service revenue increased $200,000, or 7.9%,
primarily as a result of the increased level of site preparation work incident
to the rental of mats.

Operating Income from Continuing Operations

     Operating income from continuing operations increased by $9.4 million, or
77.9%, to total $21.5 million in the 1995 period, compared to $12.1 million in
the prior year.  This represents an improvement in operating margin to 20.4% in
1995, compared to 14.0% in 1994.

     Primary components of the increase included: (i) approximately $2.9 million
related to the effect of volume increases in both NOW and NORM processing; (ii)
$3.6 million from increased mat rerentals; (iii) $1.3 million resulting from the
increase in the volume of mats rented, to approximately 200 million board feet,
compared to 157 million board feet in 1994, at similar margins; and (iv) an
approximate $200,000 increase in operating profit on a better gross margin mix
from wood product sales.

     The decline of $573,000 in general and administrative expenses primarily
reflects the impact of approximately $600,000 of prior year charges for legal
costs incurred in an appeal of an expropriation matter. 

                                       37
<PAGE>
 
Additionally, the provision for uncollectible accounts was $797,000 less in the
1995 period as compared to the 1994 period.

Interest Expense

     Interest expense increased to $3.8 million in 1995, from $2.7 million in
1994.  The increase is a result of an increase in borrowings, proceeds of which
were used to fund continued additions to productive capacity, including
Newpark's waste processing facilities, its prefabricated mats and additions to
inventory, primarily at the sawmill facility.

Non-Recurring Expense

     Results for 1995 include $436,000 of non-recurring costs associated with a
proposed merger which was not completed.

Provision for Income Taxes

     During 1995, Newpark recorded an income tax provision of $5.0 million, or
28.3% of pre-tax income.  While Newpark's net operating loss carryforwards
remain to be used for income tax return purposes, for financial reporting
purposes, substantially all of the remaining net operating loss and tax credit
carryforwards applicable to federal taxes were recognized in the first half of
the year, which reduced the effective tax rate for that portion of the year.
During 1994, Newpark recorded a tax benefit of $252,000 as a result of the
availability of net operating loss carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

     Newpark's working capital position remained relatively constant during the
year ended December 31, 1996, and increased by $27.9 million during the nine
months ended September 30, 1997.  Key working capital data is provided below:

     For the nine months ended September 30, 1997, Newpark's working capital
needs were met primarily from operating cash flow and borrowings under the
Credit Facility.  Total cash generated from  operations of $28.1 million was
supplemented by $32.2 million from financing activities, to provide for a total
of $56.3 million used in investing activities, including for the purchase of
drilling fluids assets, the purchase of mats and the expansion of waste disposal
facilities.

     On August 12, 1996, Newpark completed the sale of 13.8 million shares of
its common stock, generating net proceeds of $98.1 million.  A total of $70.5
million was used to complete the acquisition of the marine-related nonhazardous
oilfield waste NOW collection operations of Campbell Wells Ltd. ("Campbell
Wells").  The remaining proceeds were used to repay $19.0 million of borrowings
under the Credit Facility and provide working capital of $8.6 million.

     During 1996, Newpark's operating activities generated $24.9 million of cash
flow.  Net proceeds of the equity offering in excess of the Campbell Wells
acquisition price, coupled with the $24.9 million generated by operations and
net new borrowings (following the offering) of $11.8 million, were used to fund

                                       38
<PAGE>
 
investing activities. Exclusive of the Campbell Wells acquisition, the majority
of the funds used in investing activities were utilized for the purchase of mats
and the expansion of waste disposal facilities, which is reflected in the
increase in property, plant and equipment.  In addition, Newpark purchased its
joint venture partners' interest in Venezuelan mat operations and purchased
additional patent rights in Newpark's proprietary business, which is reflected
in the increase in other assets.

     During 1996, Newpark sold the facility and certain equipment of its former
marine service business to the operator of that business.  These assets were
being leased by the operator and were subject to debt obligations, which were
assumed by the purchaser at closing.  In addition to the extinguishment of these
debt obligations, Newpark received $1.2 million in cash in the transaction.
Newpark also has guaranteed certain of the debt obligations of the operator,
which is limited to a maximum of $10.0 million and reduces proportionately with
debt repayments made by the operator.

     On June 30, 1997, Newpark entered into the Credit Facility, which provides
for a $90.0 million revolving credit facility maturing on June 30, 2000,
including up to $5.0 million in standby letters of credit.  At September 30,
1997, $2.0 million in letters of credit were issued and outstanding under the
Credit Facility, and an additional $73.7 million was outstanding under the
revolving facility.  Amounts outstanding under the Credit Facility bear interest
at either (i) a specified prime rate or (ii) the LIBOR rate plus a spread which
is determined quarterly based upon the ratio of Newpark's funded debt to EBITDA
(as defined in the Credit Facility).  The Credit Facility requires that Newpark
maintain certain specified financial ratios and comply with other usual and
customary requirements.  Newpark was in compliance with all of the covenants in
the Credit Facility at September 30, 1997.  On November 7, 1997, the Credit
Facility was amended to provide for a $10.0 million special advance note, which
was treated as an additional advance under the Credit Facility.  The proceeds of
the special advance note were used to acquire certain assets of Anchor Drilling
Fluids USA, Inc. ("Anchor Drilling").  The Credit Facility was further amended,
effective upon the closing of this 144A Notes Offering,  to provide for the
release of the security interests in certain of Newpark's assets previously
granted to the lenders under the Credit Facility and to permit the sale of the
144A Notes.  Newpark used the net proceeds from the 144A Notes Offering to repay
all borrowings outstanding under the Credit Facility, including the special
advance note.  See "Use of Proceeds" and "Description of Certain Other
Indebtedness."

     Newpark anticipates capital expenditures of approximately $17 million
during the fourth quarter of 1997, including: (i) $10 million for the
acquisition of certain assets of Anchor Drilling; (ii) $3 million to expand
barite milling capacity; (iii) $3 million for the upgrade and purchase of
equipment; and (iv) $1 million for the purchase of additional hardwood mats.
For 1998, Newpark anticipates capital expenditures of approximately $70 million,
including:  (i) $10 million to acquire and develop additional injection well
sites, (ii) $15 million for expansion of drilling fluids operations, including
the purchase of equipment associated with fluids processing and recycling and
infrastructure expansions; (iii) $8 million to expand barite milling capacity;
(iv) $15 million for the purchase of additional hardwood mats; (v) $4 million
for the development of Newpark's synthetic mat system; (vi) $10 million for the
upgrade and purchase of equipment; and (vii) $8 million for expansion into
industrial waste disposal markets.  After taking into account the application of
the proceeds from the 144A Notes Offering as described in "Use of Proceeds",
Newpark anticipates that all of such capital expenditures will be satisfied with
the remaining proceeds from the 144A Notes Offering, borrowings under the Credit
Facility and cash flow from operations.
 
     Newpark presently has no commitments beyond the Credit Facility by which it
could obtain additional funds for current operations; however, it regularly
evaluates potential borrowing arrangements which may be utilized to fund future
expansion plans. Newpark believes that available borrowings under the Credit
Facility and internally generated funds will be sufficient to support its
working capital, capital expenditure and debt service requirements for at least
the next 12 months. Except as described in the preceding

                                       39
<PAGE>
 
paragraph, Newpark is not aware of any material capital expenditures,
significant balloon payments or other payments on long-term obligations or any
other demands or commitments, including off-balance sheet items, to be incurred
beyond the next 12 months.

     Inflation has not materially impacted Newpark's revenues or income.

Deferred Tax Asset

     Newpark accounts for income taxes in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes".  This
standard requires, among other things, recognition of future tax benefits
measured by enacted tax rates attributable to deductible temporary differences
between the financial statement and income tax basis of assets and liabilities
and to tax net operating loss and credit carryforwards to the extent that
realization of such benefits is more likely than not.  Newpark believes that the
recorded deferred tax assets ($3.1 million at September 30, 1997) are realizable
through reversals of existing taxable temporary differences.

                                    BUSINESS

GENERAL

     Newpark is a leading provider of integrated environmental and oilfield
services to the oil and gas exploration and production industry in the U.S. Gulf
Coast area, principally in Louisiana and Texas. Services provided, either
individually or as part of a comprehensive package, include: (i) oilfield waste
services utilizing patented and proprietary technology, including processing and
disposing of nonhazardous oilfield waste ("NOW") and oilfield waste that is
contaminated with naturally occurring radioactive material ("NORM"); (ii)
drilling fluids products and services and related engineering and technical
services; (iii) mat rentals and sales in which patented prefabricated wooden
mats are used as temporary access roads and worksites in oilfield and other
construction applications; and (iv) other environmental and integrated oilfield
services, including construction, design and engineering services.  In order to
take advantage of many customers' increasing focus on outsourcing and vendor
consolidation, Newpark has integrated its drilling fluids products and services
with its waste disposal and mat services to provide a "one-stop shop" approach
to solving customers' problems.  For the twelve months ended September 30, 1997,
Newpark had total revenues of $194.1 million, and EBITDA of $81.0 million.

     Newpark collects, processes and disposes of oilfield waste, primarily NOW
and NORM.  Newpark processes NOW received at its facilities primarily for
injection into environmentally secure geologic formations deep underground and,
to a lesser extent, for disposal at certain landfarming facilities.  NOW that is
not injected or landfarmed is processed by Newpark into a product which is used
as intermediate daily cover material or cell liner and construction material at
municipal waste landfills.  In 1994, Newpark began processing and disposing of
NORM waste.  Since June 1996, Newpark has operated under a license authorizing
the direct injection of NORM into disposal wells at Newpark's Big Hill, Texas
facility, the only offsite facility in the U.S. Gulf Coast licensed for the
direct injection of NORM.

     Newpark is a full-service provider of drilling fluids and associated
engineering and technical services to the onshore and offshore oil and gas
exploration industry in the Gulf Coast areas of Louisiana and Texas. Newpark
focuses on providing unique solutions to highly technical drilling projects
involving complex conditions, as these projects require critical engineering
support of the fluids system during the drilling process to ensure optimal
performance at the lowest total well cost.  Newpark has established its own
barite grinding capacity to provide a source of critical raw materials for its
drilling fluids operations.  Additionally, Newpark has initiated a process to
recycle a portion of the drilling fluids received as waste in its NOW disposal
business to (i) recover barite and other key chemical components for reuse in
the production of drilling fluids, (ii) reduce the cost of materials in
producing drilling fluids and (iii) expand Newpark's supply of drilling fluids.

     In its mat business, Newpark uses patented interlocking wooden mat systems
to provide temporary access roads and worksites in unstable soil conditions,
primarily in support of oil and gas exploration operations along the U.S. Gulf
Coast.  In response to increasing environmental regulations, in 1994, Newpark
began marketing its mat services for use in the construction of pipelines,
electrical distribution systems and highways in and through wetlands
environments.  As a result, this new market for Newpark's mat business has
broadened the geographic area served by Newpark to include the coastal areas of
the Southeastern U.S., particularly Florida and Georgia.  Newpark also markets
its mat services to the oil and gas exploration industries in Venezuela and
Algeria.

     Newpark also provides a comprehensive range of other environmental services
for its customers' oil and gas exploration and production activities, including
site assessment, waste pit design, construction 

                                       41
<PAGE>
 
and installation, regulatory compliance assistance, site remediation and site
closure, oilfield construction services, hook-up and connection of wells and
installation of production equipment.

INDUSTRY FUNDAMENTALS

     Demand for Newpark's environmental and oilfield services is being driven by
three significant trends:  (i) increasing oil and gas exploration and production
expenditures and activity; (ii) more complex drilling techniques, which tend to
generate more waste; and (ii) increasing environmental regulation of NOW and
NORM.  The demand for all of Newpark's services is heightened with increased oil
and gas drilling activity.  According to the Baker-Hughes Rotary Rig Count, the
number of drilling rigs working in the U.S. Gulf Coast region recently reached
its highest level since 1990, and the average rig count in the region for the
nine month period ended on September 30, 1997 was the highest average since
1985.

     Newpark believes that technological advances that have reduced the risk and
cost of finding oil and gas are an important factor in the recent upturn.  These
advances include the use of three dimensional seismic data and the computer-
enhanced interpretation of this data, which increases the likelihood of drilling
a successful well, and improved drilling tools and drilling fluids, which
facilitate faster drilling and reduce the overall cost of the well.  These
advances also have increased the willingness to drill in coastal marshes and
inland waters, and to dig deeper wells at larger locations. Such projects rely
heavily on services such as Newpark's integrated environmental services. Deeper
wells require the construction of larger locations to accommodate the drilling
equipment and the equipment for handling drilling fluids and associated wastes,
and generally are in service for significantly longer periods and generate
additional mat rental revenues. Deeper wells also require more chemically
complex drilling fluids programs, which generate wastes that are more difficult
and costly to dispose of than wastes generated by simpler systems used in
shallower wells. Newpark believes that deeper drilling has contributed
significantly to the increased demand for Newpark's services.

     The oilfield market for environmental services has experienced growth due
to increased regulatory activity regarding the disposal of exploration and
production wastes.  Louisiana, Texas and other states have enacted comprehensive
laws and regulations governing the proper handling of NOW and NORM, and
regulations have been proposed in other states.  As a result, generators of
waste and landowners have become increasingly aware of the need for proper
treatment and disposal of such waste in both the drilling of new wells and the
remediation of production facilities.

     For many years, prior to current regulation, industry practice was to allow
NOW to remain in the environment.  Onshore, surface pits were used for the
disposal of NOW; offshore or in inland waters, NOW was discharged directly into
the water.  As a result of increasing public concern over the environment, NOW
has in recent years become subject to public scrutiny and governmental
regulation.  Operators of exploration and production facilities, including major
and independent oil companies, have found themselves subject to numerous laws
and regulations issued by both state and federal agencies. These laws and
regulations have imposed strict requirements for ongoing drilling and production
activities in certain geographic areas, as well as for the remediation of sites
contaminated by past disposal practices and, in many respects, have prohibited
the prior disposal practices.  In addition, operators have become increasingly
concerned about possible long-term liability for remediation, and landowners
have become more aggressive about land restoration.  For these reasons,
operators are increasingly retaining service companies, such as Newpark, to
devise and implement comprehensive waste management techniques to handle waste
on an ongoing basis and to remediate past contamination of oil and gas
properties.

                                       42
<PAGE>
 
     Regulations and several permits issued under the Clean Water Act have
continued the trend towards more stringent regulation of NOW.  During September
1996, the comment period was ended on proposed "zero-discharge" regulations for
the territorial seas subcategory (corresponding to state territorial waters) of
the Gulf of Mexico.  Zero-discharge regulations affecting production waste in
the coastal subcategory (generally including inland waters and transition zone
onshore areas) became effective January 15, 1997. While limited temporary
exemptions have been granted to some oil companies by state regulators, these
actions have been opposed by leading environmental groups.  In addition, several
lawsuits have been filed challenging the validity of these regulations.
Accordingly, the timing of the implementation of these regulations is uncertain.

     Late in 1992, the Louisiana Department of Environmental Quality ("DEQ")
promulgated and began to enforce new, stricter limits on the level of radium
concentration above which NOW became categorized as NORM.  NORM regulations
require more stringent worker protection, handling and storage procedures than
those required of NOW under Louisiana regulations.  The Texas Railroad
Commission also has adopted final rules governing the disposal of NORM.
Adoption of final regulations has resolved the regulatory uncertainty associated
with NORM in Louisiana and Texas.  Similar regulations have been promulgated in
the States of Mississippi, New Mexico and Arkansas.  Draft regulations are
presently being reviewed in Oklahoma.

BUSINESS STRENGTHS

     Proprietary Products and Services.  Over the past 15 years, Newpark has
acquired and developed, and continues to improve, patented or proprietary
technology and know-how which have enabled the Company to provide innovative and
unique solutions to oilfield construction and waste disposal customers. Newpark
believes that increased customer acceptance of its proprietary products and
services has enabled it to take advantage of the recent upturn in drilling and
production activity.

     Injection of Waste.  Since 1992, Newpark has developed and used proprietary
technology to dispose of NOW by low-pressure injection into unique geologic
structures deep underground.  In December 1996, Newpark was issued process
patents covering its NOW and NORM waste processing and injection operations.
Newpark believes that its proprietary injection technology is currently the most
cost-effective method for the offsite disposal of oilfield wastes.
Additionally, Newpark believes that its proprietary injection technology is
suitable for the disposal of other types of waste, and Newpark recently has
filed an application to expand into the nonhazardous industrial waste market.

     Patented Mats.  Newpark owns or licenses several patents that cover its
wooden mats and subsequent improvements.  To facilitate entry into new markets
and reduce the Company's dependence on the supply of hardwoods, Newpark obtained
the exclusive license for a new patented synthetic mat designed from recycled
plastics and other synthetic materials and has begun the development of a
manufacturing facility to produce such synthetic mats.

     Low Cost Infrastructure.  Newpark has assembled an infrastructure covering
the entire U.S. Gulf Coast region, including injection disposal sites, transfer
stations, barges, mat inventories, mat service centers, hardwood supplies for
the construction of mats, and barite supplies for the make-up of drilling
fluids. Newpark believes that it owns, leases or has options to acquire a
majority of the available injection disposal sites in the U.S. Gulf Coast
suitable for its proprietary injection methods.  Newpark also owns or leases
under long-term charter 43 of the 53 barges currently licensed to transport NOW
and NORM.  Newpark built a substantial portion of its infrastructure during the
depressed market conditions that prevailed prior to 1996 

                                       43
<PAGE>
 
and believes that, under current market conditions, its infrastructure could be
duplicated only at significantly higher cost.

     Integration of Services.  Newpark believes that it is one of the few
companies in the U.S. Gulf Coast able to provide a package of integrated
services and offer a "one-stop shop" approach to solving customers' problems.
Newpark's mats provide the access roads and worksites for a majority of the land
drilling in the Gulf Coast market, and on-site and off-site waste management
services are frequently sold in combination with mat services.  Newpark's entry
into the drilling fluids business has created the opportunity for it to recycle
used drilling fluids and to market drilling fluids with other drilling services,
including construction services, related technical and engineering services,
disposal of used fluids and other waste material, site cleanup and site closure.
Consequently, Newpark believes that it is uniquely positioned to take advantage
of the industry trend towards outsourcing and vendor consolidation.

     Experience in Regulatory Environment.  Newpark believes that its operating
history provides it with a competitive advantage in the highly regulated
oilfield waste disposal business.  As a result of working closely with
regulatory officials and citizens' groups, Newpark has gained acceptance for its
proprietary injection technology and has received a series of permits for the
Company's disposal facilities, including a permit allowing the direct injection
of NORM at Newpark's Big Hill, Texas facility.  These permits enable Newpark to
expand its business and operate cost-effectively.  Newpark believes that its
proprietary injection method is superior to alternative methods of disposal of
oilfield wastes, including landfarming, because injection provides greater
assurance that the waste is permanently disposed of and will not contaminate the
surrounding property and groundwater.  Newpark further believes that increasing
environmental regulation and activism will inhibit the widespread acceptance of
other disposal methods and the permitting of additional disposal facilities.

     Experienced Management Team.  Newpark's executive and operating management
team has built and augmented Newpark's capabilities over the past ten years,
allowing it to develop a base of knowledge and a unique understanding of the
oilfield construction and waste disposal markets.  Newpark's executive and
operating management team has an average of 22 years of industry experience, and
an average of eight years with Newpark, including several who have been with
Newpark for 20 years or more.  Newpark also has strengthened its management team
by attracting additional experienced personnel and by retaining key management
personnel of the companies it has acquired.

BUSINESS STRATEGY

     Service and Product Extensions.  Newpark believes that it can apply the
waste processing and injection technology it has pioneered and developed in the
oil and gas exploration industry to other industrial waste markets.  Initially,
Newpark intends to focus on wastes generated in the petrochemical processing and
refining industries, as many potential customers in these industries are located
in the markets already served by Newpark, and certain wastes generated by these
industries have many of the same characteristics as the NOW waste currently
handled by Newpark.  In addition, Newpark will continue to evaluate the
applicability of its injection disposal methods to other industrial waste
streams.  Newpark is pursuing the development of a synthetic mat system to
enhance its current mat fleet and expand into new markets.  Newpark believes
that synthetic mats may have certain military and emergency response
applications.

     Implement Newpark's Total Fluids Management Concept.  Newpark's strategy is
to integrate its operations to provide a "one-stop shop" approach to solving
customers' problems.  By integrating its drilling fluids and waste disposal
services with other on-site fluids management and solids control services,
Newpark intends to provide a comprehensive solution to the management of the
total fluids stream.  Newpark calls 

                                       44
<PAGE>
 
this concept "Total Fluids Management" and believes that its ability to provide
a comprehensive package of products and services reduces the total cost to the
customer and increases operating efficiency.

     Geographic Expansion.  Newpark believes that significant expansion
opportunities exist in each of its product lines, both in domestic markets and
in selected foreign markets.  Newpark intends to expand its oilfield waste
disposal operations domestically into West Texas and the Permian Basin, with
initial international expansions planned for Mexico and Venezuela.  As part of
this strategy, Newpark seeks to continue to add disposal capacity, including new
injection wells, throughout the U.S. Gulf Coast region, in order to more
efficiently serve its customers.  Newpark intends to expand its drilling fluids
business through acquisitions and internal growth to the offshore Gulf of
Mexico, the mid-continent and Permian Basin regions of the United States, and,
internationally, to Mexico, Venezuela and Canada.  In its domestic mat business,
Newpark will continue to capitalize on environmental regulations affecting the
construction of pipelines, electrical distribution systems and highways in and
through wetlands and other environmentally sensitive locations.
Internationally, Newpark intends to expand its mat operations in Venezuela and
Algeria and review expansion opportunities in other parts of Africa, South
America, Europe and Asia.

     Cost Reductions.  Newpark will continue to pursue a strategy of reducing
costs in its existing operations to increase margins.  Newpark intends to expand
the use of washwater recycling facilities and the recycling of oilfield waste
from its NOW disposal business for use in its drilling fluids business, as these
methods will allow Newpark to reduce the volume of waste transported and
disposed of in its injection wells. Newpark also believes that recycling of
oilfield waste from its NOW disposal business will provide it with a low-cost
source of raw materials for the production of its drilling fluids.  Newpark
intends to continue to consolidate supply and purchasing functions in its
drilling fluids business to eliminate duplicate costs, better utilize its
existing asset base and take advantage of manufacturer direct pricing, volume
discounts and direct rail transportation.

DESCRIPTION OF BUSINESS

  Offsite Waste Processing

     NOW Waste Processing.  Generally under state regulation, if NOW cannot be
treated for discharge or disposed of on the location where it is generated, it
must be transported to a licensed NOW disposal or treatment facility.  Three
primary alternatives for offsite disposal of NOW are available to generators in
the U.S. Gulf Coast: (i) underground injection (see "Injection Wells"); (ii)
land-farming; and (iii) processing and conversion of the NOW into a reuse
product.  In addition, a portion of the NOW can be recycled into a drilling
fluids product.

     Newpark processed and disposed of 4,142,000 barrels of NOW in the first
three quarters of 1997, of which 4,061,000 barrels were generated from current
drilling and production operations and 81,000 barrels were generated from the
remediation of old pits and production facilities, compared with 2,403,000
barrels in the first three quarters of 1996, of which 2,264,000 were from
current drilling and production operations and 139,000 were from remediation
activities.  Newpark processed and disposed of 3,956,000 barrels of NOW in 1996,
of which 3,588,000 barrels were generated from current drilling and production
operations and 368,000 barrels were generated from the remediation of old pits
and production facilities, compared with 2,905,000 barrels in 1995, of which
2,364,000 were from current drilling and production operations and 541,000 were
from remediation activities.

     In August 1996, Newpark completed the acquisition of  substantially all of
the marine-related NOW collection operations, excluding landfarming facilities
and associated equipment, of Campbell Wells, a 

                                       45
<PAGE>
 
wholly-owned subsidiary of Sanifill, Inc. In the acquisition, Newpark acquired
certain leases associated with five transfer stations located along the U.S.
Gulf Coast and three receiving docks at the landfarm facilities operated by
Campbell Wells. Newpark is subject to an agreement with Campbell Wells under
which an agreed annual quantity of NOW must be delivered to the Campbell Wells'
landfarming facilities for a period of 25 years. The landfarms are now operated
by U.S. Liquids, Inc. The Campbell Well's acquisition significantly increased
Newpark's NOW disposal business and disposal capacity.

     Including the facilities acquired from Campbell Wells, Newpark operates ten
receiving and transfer facilities located along the U.S. Gulf Coast from Venice,
Louisiana, to Corpus Christi, Texas.  Waste products are collected at the
transfer facilities from three distinct markets: offshore exploration and
production; land and inland waters exploration and production; and remediation
of existing or inactive well sites and production facilities.  These facilities
are supported by a fleet of 43 double-skinned barges certified by the U. S.
Coast Guard to transport NOW.  Waste received at the transfer facilities is
transported by barge through the Gulf Intracoastal Waterway to Newpark's
processing and transfer facility at Port Arthur, Texas, and trucked to injection
disposal facilities at Fannett, Texas.  Since the third quarter of 1995, the
Fannet facility has served as Newpark's primary NOW injection facility.

     Before 1994 a large portion, and in 1995 and later years, a small portion
of the waste stream received by Newpark has been converted into a commercial
reuse product meeting the specifications under applicable federal and state
regulations for reuse as a covering material or cell liner material and for
other construction purposes at sanitary landfills.  Under applicable
regulations, landfills must cover the solid waste deposited daily with earth or
other inert material.  Newpark's reuse product is deposited at either the City
of Port Arthur Municipal Landfill or the City of Beaumont Municipal Landfill for
use as cover or construction material pursuant to contracts with the respective
cities.  This reuse is conducted under authorization from the Texas Natural
Resources Conservation Commission.  Increased injection capacity and access to
the Campbell Wells landfarms has reduced the volume of waste delivered to these
landfills as a reuse product. Newpark also has developed alternative uses for
the product as roadbase material or construction fill material.

     NORM Processing and Disposal.  Many alternatives are available to the
generator for the treatment and disposal of NORM.  These include both chemical
and mechanical methods designed to achieve volume reduction, on-site burial of
encapsulated NORM within old well bores and soil washing and other techniques of
dissolving and suspending the radium in solution for onsite injection of NORM
liquids.  When the application of these techniques are not economically
competitive with offsite disposal, or insufficient to bring the site into
compliance with applicable regulations, the NORM must be transported to a
licensed storage or disposal facility.  A significant factor contributing to the
growth in the market has been increased litigation on the part of landowners who
contend that their property has been damaged by past practices of the oil and
gas industry.  In some cases, settlement of the litigation has mandated the
remediation of such sites.  In addition, these lawsuits have caused other
operators to dispose of NORM waste offsite to avoid the threat of future
litigation.  While litigation has contributed to increased offsite NORM
disposal, the project oriented nature of the market makes it difficult to
predict the timing of revenues.

     Newpark's initial NORM processing facility in Port Arthur, Texas was
licensed in September 1994 and began operations October 21, 1994.  On May 21,
1996, Newpark was awarded a new license permitting receipt of NORM waste and
direct injection disposal of NORM at its Big Hill, Texas facility, eliminating
the need to process the waste until it attains NOW characteristics, as was the
case at the Port Arthur facility. Additionally, since the processing facility
and the disposal wells are now permitted to be located at the same site,
transportation costs are minimized.  The new license also allows injection of
more concentrated NORM into the wells, subject only to Newpark's facility
contamination limits.  As a result, the capacity and useful 

                                       46
<PAGE>
 
life of the site has been extended and costs have been reduced. The new license
has allowed Newpark to reduce prices to customers and encourage the use of the
direct injection process for the disposal of large volumes of NORM. During the
nine months ended September 30, 1997, Newpark received 24,700 barrels of NORM
contaminated waste, as compared to 118,600 barrels during the nine months ended
September 30, 1996, while 143,500 barrels were received in 1996 and 70,000
barrels were received in 1995.

     Injection Wells.  Newpark's injection technology is distinguished from
conventional methods in that it utilizes very low pressure, typically under 100
pounds per square inch, to move the waste into the injection zone.  Conventional
wells typically use pressures as high as 2,000 pounds per square inch.  In the
event of a formation failure or blockage of the face of the injection zone, such
pressure can force waste material beyond the intended zone, posing a potential
hazard to the environment.  The low pressure used by Newpark is inadequate to
drive the injected waste from its intended geologic injection zone.

     In February 1993, upon receipt of a permit from the Texas Railroad
Commission, Newpark began development of a 50 acre injection well facility in
the Big Hill Field in Jefferson County, Texas.  Three wells were initially
installed at the Big Hill facility and three additional wells have since been
successfully completed.  During 1995, Newpark licensed and constructed a new
injection well facility at a 400 acre site near Fannett, Texas, which was placed
in service in September 1995 and now serves as Newpark's primary facility for
the disposal of NOW.  The Fannett facility currently includes three injection
wells and a processing plant which is used to reduce and make uniform the size
of the particles in the waste stream to maintain desired flow characteristics in
Newpark's injection wells.  Because of differences between the geology and
physical size of the two sites, the Fannett site is expected to provide greater
capacity than the Big Hill site.  The injection wells at Fannett receive NOW
waste from Newpark's processing facilities at Port Arthur, as well as from
customers in the surrounding area.  Newpark also has completed a bulk barge
unloading facility adjacent to its Port Arthur processing plant.  During 1997,
Newpark installed a washwater recycling plant at one of its transfer stations
and determined to install such a plant at all of its facilities. Newpark
believes the use of this process could materially reduce the volume of washwater
created by its operations and thereby reduce disposal costs.

     Newpark anticipates that it will open additional injection facilities for
both NOW and NORM waste in Louisiana, Mississippi and Texas over the next two to
three years. In January 1997, Newpark acquired an additional injection facility,
which includes two active injection wells on 37 acres of land adjacent to the
Big Hill facility, and in October 1997, Newpark acquired four facilities in the
Permian Basin at which brine is extracted and sold and NOW is disposed of in the
salt domes or caverns created by the extraction process. Newpark has identified
a number of additional sites in the U.S. Gulf Coast region as suitable for
development of such disposal facilities, has received permits for one additional
site in Texas, and plans to file for additional permit authority in Louisiana.
Newpark believes that its current processing and disposal capacity will be
adequate to provide for expected future demand for its oilfield waste disposal
and other environmental services.

     Newpark believes that its patented injection technology has application to
other industrial waste markets and waste streams.  In January 1997, Newpark
acquired 120 acres of land adjacent to its Big Hill facility, which it plans to
develop into an industrial waste disposal facility.  Initially, Newpark intends
to focus on wastes generated in the petrochemical processing and refining
industries.

  Drilling Fluids

     Providing full drilling fluids service to its customers is a key step
towards implementation of Newpark's Total Fluids Management strategy.  Newpark
focuses on highly technical drilling projects 

                                       47
<PAGE>
 
involving complex conditions, such as deep horizontal drilling or deep water
drilling. These projects require constant monitoring and critical engineering
support of the fluids system during the drilling process in order to ensure
optimal performance at the lowest total well cost.

     In February 1997, Newpark completed the acquisition of SBM (now known as
Newpark Drilling Fluids, Inc.), a full-service provider of drilling fluids and
associated engineering and technical services to the onshore and offshore oil
and gas exploration industry in the Louisiana and Texas Gulf Coast regions.
Since completion of the SBM acquisition, Newpark has expanded its drilling
fluids operations through additional acquisitions in order to provide a full
range of drilling fluids services.  These acquisitions included four retail
drilling fluids companies, one wholesale drilling fluids company and one
specialty chemical company.  Newpark also has recently completed the acquisition
of certain assets of Anchor Drilling in Louisiana and Texas, which will
significantly enhance Newpark's presence in the offshore Gulf of Mexico. Newpark
intends to continue to expand its drilling fluids operations through
acquisitions and internal expansion.

     In May 1997, Newpark acquired a specialty milling company that grinds
barite and other industrial minerals at facilities in Houston, Texas and New
Iberia, Louisiana.  The acquisition provides Newpark with a source of critical
raw materials for its drilling fluids operations.  Additionally, Newpark is
implementing a program to recycle a portion of the drilling fluids received as
waste in its NOW disposal business, thereby recovering barite and other key
chemical components for reuse in the production of drilling fluids.  Newpark
believes that this recycling reduces the costs of materials in producing
drilling fluids and expands the available supply of drilling fluids.  Recycling
also helps reduce the volume of NOW waste transported and disposed of by Newpark
in its disposal operations.

  Mat Rental and Sales

     In 1988, Newpark acquired the right to use, in Louisiana and Texas, a
patented prefabricated interlocking mat system for the construction of drilling
and work sites, which has displaced use of individual hardwood boards.  This
system is quicker to install and remove than individual hardwood boards,
substantially reducing labor costs.  Prefabricated mats are also stronger,
easier to repair and maintain, and generate less waste material during
construction and removal.  In 1994, Newpark acquired the exclusive right to use
this system in the continental U.S. for the life of the patent.  The patent is
currently set to expire in 2003.  Modifications have been made to the patent,
and Newpark has filed an application, which, if granted, would significantly
extend the life of the patent.  The original holder of the patent continues to
fabricate the mats for Newpark and acts as a distributor of mats for non-
oilfield applications.

     Newpark provides its mat services in two primary markets:

  Oilfield Market.  Newpark provides this patented interlocking mat system to
the oil and gas industry to ensure all-weather access to exploration and
production sites in the unstable soil conditions common along the onshore Gulf
of Mexico.  The mats are generally rented to the customer for an initial period
of 60 days; after that time, additional rentals are earned on a monthly basis
until the mats are released by the customer.

  Wetlands Use.  Beginning in 1994, Newpark recognized the development of
another market use for its patented mat system in providing access roads and
temporary work sites to the pipeline, electrical utility and highway
construction industries, as Newpark believes its mats are well suited for use in
wetlands and other areas characterized by unstable soil conditions.  Demand for
these services was spurred by Federal Energy Regulatory Commission orders
requiring compliance with environmental protection rules under the Clean Water
Act in the pipeline construction business, and since 1995, Newpark has performed
projects in

                                       48
<PAGE>
 
connection with pipeline, electrical utility and highway construction projects
in Georgia, Florida, Texas and Louisiana. Revenue from this source was
approximately $2.4 million in 1994, approximately $7.0 million in 1995 and
approximately $5.8 million during 1996. During the nine months ended September
30, 1997, Newpark received approximately $1.0 million in revenue from non-
oilfield mat rentals, as Newpark believes capital expenditures in the electric
utility industry have been delayed while the industry adjusts to deregulation.

     Rerentals and Sales.  Drilling and work sites are typically rented by the
customer for an initial period of 60 days.  Often, the customer extends the
rental term for additional 30 day periods, resulting in additional revenues to
Newpark.  These rerental revenues provide high margins because only minimal
incremental depreciation and maintenance costs accrue to each rerental period.
Factors which may increase rerental revenue include: (i) the trend toward
increased activity in the "transition zone"; (ii) a trend toward deeper
drilling, taking a longer time to reach the desired target; and, (iii) the
increased frequency of commercial success, requiring logging, testing, and
completion (hook-up), extending the period during which access to the site is
required.  In the opinion of industry analysts, application of advanced
technologies, particularly the use of three-dimensional seismic data, has
contributed to these trends.  Occasionally, the mats are purchased by the
customer when a site is converted into a permanent worksite.

     Venezuela.  The Venezuelan government has enacted legislation designed to
speed the opening of its petroleum sector to foreign investment, including
international oil companies, in furtherance of a national objective of
increasing that country's production of oil to five million barrels per day by
the year 2005. Many of the international oil companies investing in Venezuela
are existing customers of Newpark.  As of September 30, 1997, Newpark had
approximately 21,000 mats in inventory in Venezuela.  Newpark expects that
activity in Venezuela will increase as further exploration concessions are
granted.

     Other International Expansion.  During 1996, Newpark shipped 4,000
interlocking mats to Algeria in an effort to develop a mat rental and sales
market in that country.  The goal is to replace the gypsum and concrete commonly
used in constructing drilling sites in the desert with a more cost effective
solution. Newpark will continue to review expansion opportunities in other parts
of Africa and South America, as well as in Europe and Asia.

     Synthetic Mats.  All of the established mat patents utilize hardwood to
construct the mat.  Newpark has acquired the rights to a patented synthetic
molded mat fabricated from recycled plastic, rubber and resins, which Newpark
believes will prove to be lighter than hardwood mats, have a longer service life
and have lower repair costs.  A limited number of pre-production samples of a
prototype mat were delivered to Newpark for testing in April 1996.  Pending
successful results in the testing program and construction by the manufacturer
of a production facility (in which Newpark is a minority partner), Newpark
expects to begin taking delivery of commercial quantities of these new mats
during 1998.  Newpark believes that the initial market for the synthetic mat
system will be certain military and emergency response type governmental sales.

  Other Integrated Services

     Promulgation and enforcement of increasingly stringent environmental
regulations affecting drilling and production sites has increased the scope of
services required by the oil companies.  Often it is more efficient for the site
operator to contract with a single company that can provide all-weather site
access and provide the required onsite and offsite environmental services on a
fully integrated basis.  Newpark provides a comprehensive range of environmental
services necessary for its customers' oil and gas exploration and production
activities.  These services include:

                                       49
<PAGE>
 
     Site Assessment.  Site assessment work begins prior to installation of mats
on a drilling site, and generally begins with a study of the proposed well site,
which includes site photography, background soil sampling, laboratory analysis
and investigation of flood hazards and other native conditions.  The assessment
determines whether the site has previously been contaminated and provides a
baseline for later restoration to pre-drilling condition.

     Pit Design, Construction and Drilling Waste Management.  Where permitted by
regulations and landowners, under its Environmentally Managed Pit ("EMP")
Program, Newpark constructs waste pits at drilling sites and monitors the waste
stream produced in drilling operations and the contents and condition of the
pits with the objective of minimizing the amount of waste generated on the site.
Where possible, Newpark disposes of waste onsite by land-farming, through
chemical and mechanical treatment of liquid waste and by annular injection into
a suitably permitted underground formation.  Waste water treated onsite may be
reused in the drilling process or, where permitted, discharged into adjacent
surface waters.

     Regulatory Compliance.  Throughout the drilling process, Newpark assists
the operator in interfacing with the landowner and regulatory authorities.
Newpark also assists the operator in obtaining necessary permits and in
complying with record maintenance and reporting requirements.

     Site Remediation.

     NOW (Drilling).  At the completion of the drilling process, under
applicable regulations, waste water on the site may be chemically and/or
mechanically treated to eliminate its waste-like characteristics and discharged
into surface waters.  Other waste that may not remain on the surface of the site
may be land-farmed on the site or injected under permit into geologic formations
to minimize the need for offsite disposal. Any waste that cannot, under
regulations, remain onsite is manifested (in Louisiana) and transported to an
authorized facility for processing and disposal at the direction of the
generator or customer.

     NOW (Production).  Newpark also provides services to remediate production
pits and inactive waste pits including those from past oil and gas drilling and
production operations.  Newpark provides the following remediation services: (i)
analysis of the contaminants present in the pit and a determination of whether
remediation is required by applicable state regulation; (ii) treatment of waste
onsite, and where permitted, reintroduction of that material into the
environment; and (iii) removal, containerization and transportation of NOW waste
to Newpark's processing facility.

     NORM.  In January 1994, Newpark became a licensed NORM contractor, allowing
Newpark to perform site remediation work at NORM contaminated facilities in
Louisiana and Texas, and recently received the first specific license to perform
NORM remediation in Arkansas.  Because of the need for increased worker-
protective equipment, extensive decontamination procedures and other regulatory
compliance issues at NORM facilities, the cost of providing such services is
materially greater than at NOW facilities and such services generate
proportionately higher revenues and operating margins than similar services at
NOW facilities.

     Site Closure. Site closure services are designed to restore a site to its
pre-drilling condition, reseeded with native grasses.  Closure also involves
delivery of test results indicating that closure has been completed in
compliance with applicable regulations.  This information is important to the
customer because the operator is subject to future regulatory review and audits.
In addition, the information may be required on a current basis if the operator
is subject to a pending regulatory compliance order.

                                       50
<PAGE>
 
     General Oilfield Construction Services.  Newpark performs general oilfield
construction services throughout the U.S. Gulf Coast area between Corpus
Christi, Texas and Pensacola, Florida.  General oilfield services performed by
Newpark include preparing work sites for the installation of mats, connecting
wells and placing them in production, laying flow lines and infield pipelines,
building permanent roads, grading, lease maintenance (the maintenance and repair
of producing well sites), cleanup and general roustabout services.  General
oilfield services are typically performed under short-term time and material
contracts, which are obtained by direct negotiation or bid.  During 1997,
Newpark acquired two oilfield site contractors, which expanded Newpark's
presence and service capabilities in the site preparation and contracting
business.

     Wood Product Sales.  Newpark purchased a sawmill in Batson, Texas, in
October 1992 in order to provide access to adequate quantities of hardwood
lumber in support of its mat business.  The mill's products include lumber,
timber, and wood chips, as well as bark and sawdust.  Pulp and paper companies
in the area supply a large proportion of the hardwood logs processed at the
sawmill and, in turn, are the primary customers for wood chips created in the
milling process.  During 1993, Newpark invested approximately $1.0 million in
expansion of the sawmill to increase its capacity for producing wood chips.
During 1995, Newpark invested an additional $750,000 to install a log watering
system to maintain the level of moisture in the wood chips produced, as desired
by its customers, and for expanded and improved sawing capacity, which improved
both production and efficiency.  Newpark believes that the capacity of the
sawmill will be sufficient to meet its anticipated needs for the foreseeable
future.

SOURCES AND AVAILABILITY OF RAW MATERIALS AND EQUIPMENT

     Newpark believes that its sources of supply for any materials or equipment
used in its businesses are adequate for its needs and that it is not dependent
upon any one supplier.  Newpark acquires the majority of its hardwood needs in
its mat business from its own sawmill, and barite used in its drilling fluids
business is provided by Newpark's specialty milling company and, to a limited
extent, by NOW  recycling.  No serious shortages or delays have been encountered
in obtaining any raw materials.

PATENTS AND LICENSES

     Newpark seeks patents and licenses on new developments whenever feasible.
On December 31, 1996, Newpark was granted a U.S. patent on its new NOW and NORM
waste processing and injection disposal system.  Newpark has the exclusive,
worldwide license for the life of the patent to use, sell and lease the
prefabricated mats that it uses in connection with its site preparation
business.  The licensor continues to fabricate the mats for Newpark and has the
right to sell mats in locations where Newpark is not engaged in business, but
only after giving Newpark the opportunity to take advantage of the opportunity
itself.  The license is subject to a royalty which Newpark can satisfy by
purchasing specified quantities of mats annually from the licensor.

     The utilization of proprietary technology and systems is an important
aspect of Newpark's business strategy.  For example, Newpark relies on a variety
of unpatented proprietary technologies and know-how in the processing of NOW.
Although Newpark believes that this technology and know-how provide it with
significant competitive advantages in the environmental services business,
competitive products and services have been successfully developed and marketed
by others.  Newpark believes that its reputation in its industry, the range of
services offered, ongoing technical development and know-how, responsiveness to
customers and understanding of regulatory requirements are of equal or greater
competitive significance than its existing proprietary rights.

                                       51
<PAGE>
 
CUSTOMERS

     Newpark's customers are principally major and independent oil and gas
exploration and production companies operating in the U.S. Gulf Coast area, with
the vast majority of Newpark's customers concentrated in Louisiana and Texas.

     During the year ended December 31, 1996, approximately 46% of Newpark's
revenues were derived from six major customers, including three major oil
companies, and one customer accounted for approximately 16% of consolidated
revenues.  During the nine months ended September 30, 1997, approximately 35% of
Newpark's revenues were derived from six major customers, including two major
oil companies, and no customer accounted for more than 10% of consolidated
revenues.  Given current market conditions and the nature of the products
involved, Newpark does not believe that the loss of any single customer would
have a material adverse effect upon Newpark.

     Newpark performs services either pursuant to standard contracts or under
longer term negotiated agreements.  As most of Newpark's agreements with its
customers are cancelable upon limited notice, Newpark's backlog is not
significant.

     Newpark does not derive a significant portion of its revenues from
government contracts of any kind.

COMPETITION

     Newpark operates in several niche markets where it is a leading provider of
services.  In Newpark's disposal business, Newpark often competes with its major
customers, who continually evaluate the decision whether to use internal
disposal methods or utilize a third party disposal company such as Newpark.
Other product markets are fragmented and highly competitive, with many
competitors providing similar products and services to the industry.  In the
drilling fluids industry, Newpark faces competition from both larger companies
that may have broader geographic coverage, and smaller companies that may have
lower capital cost structures.

     Newpark believes that the principal competitive factors in its businesses
are price, reputation, technical proficiency, reliability, quality, breadth of
services offered and managerial experience.  Newpark believes that it
effectively competes on the basis of these factors and that its competitive
position benefits from its proprietary position with respect to the patented mat
system used in its site preparation business, its proprietary treatment and
disposal methods for both NOW and NORM waste streams and its ability to provide
its customers with an integrated well site management program including
environmental, drilling fluids and general oilfield services.  Additionally, it
is often more efficient for the site operator to contract with a single company
that can prepare the well site and provide the required onsite and offsite
environmental services.  Newpark believes that its ability to provide a number
of services as part of a comprehensive program enables Newpark to price its
services competitively.

ENVIRONMENTAL DISCLOSURES

     Newpark has sought to comply with all applicable regulatory requirements
concerning environmental quality.  Newpark has made, and expects to continue to
make, the necessary capital expenditures for environmental protection at its
facilities, but does not expect that these will become material in the
foreseeable future.  No material capital expenditures for environmental
protection were made during 1996 or the first nine months of 1997.

                                       52
<PAGE>
 
     Newpark derives a significant portion of its revenue from providing
environmental services to its customers.  These services have become necessary
in order for these customers to comply with regulations governing the discharge
of materials into the environment.  Substantially all of Newpark's capital
expenditures made in the past several years, and those planned for the
foreseeable future, are directly or indirectly influenced by the needs of
customers to comply with such regulations.

EMPLOYEES

     At September 30, 1997, Newpark employed approximately 906 full and part-
time personnel, none of which are represented by unions.  Newpark considers its
relations with its employees to be satisfactory.

ENVIRONMENTAL REGULATION

     Newpark deals primarily with NOW and NORM in its waste disposal business.
NOW and NORM are generally described as follows:

          NOW.  Nonhazardous Oilfield Waste, or NOW, is waste generated in the
exploration for or production of oil and gas. These wastes typically contain
levels of oil and grease, salts or chlorides, and heavy metals in excess of
concentration limits defined by state regulators.  NOW also includes soils which
have become contaminated by these materials.  In the environment, oil and grease
and chlorides disrupt the food chain and have been determined by regulatory
authorities to be harmful to plant and animal life.  Heavy metals are toxic and
can become concentrated in living tissues.

          NORM.  Naturally Occurring Radioactive Material, or NORM, is present
throughout the earth's crust at very low levels.  Among the radioactive
elements, only Radium 226 and Radium 228 are slightly soluble in water.  Because
of their solubility, which can carry them into living plant and animal tissues,
these elements present a hazard.  Radium 226 and Radium 228 can be leached out
of hydrocarbon bearing strata deep underground by salt water which is produced
with the hydrocarbons.  Radium generally precipitates out of the production
stream as it is drawn to the surface and encounters a pressure or temperature
change in the well tubing or production equipment, forming a rust-like scale.
This scale contains radioactive elements which, over many years, can become
concentrated on tank bottoms or at water discharge points at production
facilities.  Thus, NORM waste is NOW that has become contaminated with these
radioactive elements above concentration levels defined by state regulatory
authorities.

     Newpark's business is affected both directly and indirectly by governmental
regulations relating to the oil and gas industry in general, as well as
environmental, health and safety regulations that have specific application to
Newpark's business.  Newpark, through the routine course of providing its
services, handles and profiles hazardous regulated material for its customers.
Newpark also handles, processes and disposes of nonhazardous regulated
materials.  This section discusses various federal and state pollution control
and health and safety programs that are administered and enforced by regulatory
agencies, including, without limitation, the U.S. Environmental Protection
Agency ("EPA"), the U.S. Coast Guard, the U.S. Army Corps of Engineers, the
Texas Natural Resource Conservation Commission, the Texas Department of Health,
the Texas Railroad Commission, the DEQ and the Louisiana Department of Natural
Resources.  These programs are applicable or potentially applicable to Newpark's
current operations.  Although Newpark intends to make capital expenditures to
expand its environmental services capabilities, Newpark believes that it is not
presently required to make material capital expenditures to remain in compliance
with federal, state and local provisions relating to the protection of the
environment.

                                       53
<PAGE>
 
          RCRA.  The Resource Conservation and Recovery Act of 1976, as amended
in 1984 ("RCRA"), is the principal federal statute governing hazardous waste
generation, treatment, storage and disposal.  RCRA and state hazardous waste
management programs govern the handling and disposal of "hazardous wastes".  The
EPA has issued regulations pursuant to RCRA, and states have promulgated
regulations under comparable state statutes, that govern hazardous waste
generators, transporters and owners and operators of hazardous waste treatment,
storage or disposal facilities.  These regulations impose detailed operating,
inspection, training and emergency preparedness and response standards and
requirements for closure, financial responsibility, manifesting of waste,
record-keeping and reporting, as well as treatment standards for any hazardous
waste intended for land disposal.

     Newpark's primary operations involve NOW, which is exempt from
classification as a RCRA-regulated hazardous waste. Many state counterparts to
RCRA also exempt NOW from classification as a hazardous waste; however,
extensive state regulatory programs govern the management of such waste. In
addition, in performing other services for its customers, Newpark is subject to
both federal (RCRA) and state solid or hazardous waste management regulations as
contractor to the generator of such waste.

     Proposals have been made in the past to rescind the exemption that excludes
NOW from regulation as hazardous waste under RCRA.  Repeal or modification of
this exemption by administrative, legislative or judicial process could require
Newpark to change significantly its method of doing business.  There is no
assurance that Newpark would have the capital resources available to do so, or
that it would be able to adapt its operations to the changed regulations.

     Subtitle I of RCRA regulates underground storage tanks in which liquid
petroleum or hazardous substances are stored.  States have similar regulations,
many of which are more stringent in some respects than the federal regulations.
The implementing regulations require that each owner or operator of an
underground tank notify a designated state agency of the existence of such
underground tank, specifying the age, size, type, location and use of each such
tank.  The regulations also impose design, construction and installation
requirements for new tanks, tank testing and inspection requirements, leak
detection, prevention, reporting and cleanup requirements, as well as tank
closure and removal requirements.

     Newpark has a number of underground storage tanks that are subject to the
requirements of RCRA and applicable state programs.  Violators of any of the
federal or state regulations may be subject to enforcement orders or significant
penalties by the EPA or the applicable state agency.  Newpark is not aware of
any existing conditions or circumstances that would cause it to incur liability
under RCRA for failure to comply with regulations applicable to underground
storage tanks.  However, cleanup costs associated with releases from these
underground storage tanks or costs associated with changes in environmental laws
or regulations could be substantial and could have a material adverse effect on
Newpark's consolidated financial statements.

          CERCLA.  The Comprehensive Environmental Response, Compensation and
Liability Act, as amended in 1986 ("CERCLA"), provides for immediate response
and removal actions coordinated by the EPA in response to certain releases of
hazardous substances into the environment and authorizes the government, or
private parties, to respond to the release or threatened release of hazardous
substances.  The government may also order persons responsible for the release
to perform any necessary cleanup. Liability extends to the present owners and
operators of waste disposal facilities from which a release occurs, persons who
owned or operated such facilities at the time the hazardous substances were
released, persons who arranged for disposal or treatment of hazardous substances
and waste transporters who selected such facilities for treatment or disposal of
hazardous substances.  CERCLA has been interpreted to create strict, 

                                       54
<PAGE>
 
joint and several liability for the costs of removal and remediation, other
necessary response costs and damages for injury to natural resources.

     Among other things, CERCLA requires the EPA to establish a National
Priorities List ("NPL") of sites at which hazardous substances have been or are
threatened to be released and that require investigation or cleanup.  The NPL is
subject to change, with additional sites being added and remediated sites being
removed from the list.  In addition, the states in which Newpark conducts
operations have enacted similar laws and keep similar lists of sites which may
be in need of remediation.

     Although Newpark primarily handles oilfield waste classified as NOW, this
waste typically contains constituents designated by the EPA as hazardous
substances under RCRA, despite the current exemption of NOW from hazardous
substance classification.  Where Newpark's operations result in the release of
hazardous substances, including releases at sites owned by other entities where
Newpark performs its services, Newpark could incur CERCLA liability.  Previously
owned businesses also may have disposed or arranged for disposal of hazardous
substances that could result in the imposition of CERCLA liability on Newpark in
the future.  In particular, divisions and subsidiaries previously owned by
Newpark were involved in extensive mining operations at facilities in Utah and
Nevada and in waste generation and management activities in numerous other
states.  These activities involved substances that may be classified as RCRA
hazardous substances.  Any of those sites or activities potentially could be the
subject of future CERCLA damage claims.

     With the exception of the sites discussed in "Environmental Proceedings"
below, Newpark is not aware of any present claims against it that are based on
CERCLA. Nonetheless, the identification of additional sites at which clean-up
action is required could subject Newpark to liabilities which could have a
material adverse effect on Newpark's consolidated financial statements.

          The Clean Water Act.  The Clean Water Act regulates the discharge of
pollutants, including NOW, into waters of the United States.  The Clean Water
Act establishes a system of standards, permits and enforcement procedures for
the discharge of pollutants from industrial and municipal waste water sources.
The law sets treatment standards for industries and waste water treatment
plants, requires permits for industrial and municipal discharges directly into
waters of the United States and requires pretreatment of industrial waste water
before discharge into municipal systems.  The Clean Water Act gives the EPA the
authority to set pretreatment limits for direct and indirect industrial
discharges.

     In addition, the Clean Water Act prohibits certain discharges of oil or
hazardous substances and authorizes the federal government to remove or arrange
for removal of such oil or hazardous substances. Under the Clean Water Act, the
owner or operator of a vessel or facility from which oil or a hazardous
substance is discharged into navigable waters may be liable for penalties, the
costs of cleaning up the discharge and natural resource damage caused by the
spill.

     Newpark treats and discharges waste waters at certain of its facilities.
These activities are subject to the requirements of the Clean Water Act, and
comparable state statutes, and federal and state enforcement of these
regulations.

     The Clean Water Act also imposes requirements that are applicable to
Newpark's customers and are material to its business.  EPA Region 6, which
includes Newpark's market, continues to issue new and amended National Pollution
Discharge Elimination System ("NPDES") general permits further limiting or
restricting substantially all discharges of produced water from the Oil and Gas
Extraction Point Source Category into waters of the United States.  These
permits include:

                                       55
<PAGE>
 
     1)  Onshore subcategory permits for Texas, Louisiana, Oklahoma and New
     Mexico issued in February, 1991 (56 Fed. Reg. 7698).  These permits
     completely prohibit the discharge of drilling fluids, drill cuttings,
     produced water or sand, and various other oilfield wastes generated by
     onshore operations into waters of the United States.  These permits have
     the effect of requiring that most oilfield wastes follow established state
     disposal programs.  These general permits expired on February 25, 1996, but
     pursuant to EPA policy, they are considered to remain in effect until
     reissued by the EPA or superseded by other EPA action.

     2)  Permits for produced water and produced sand discharges into coastal
     waters of Louisiana and Texas issued on January 9, 1995 (60 Fed. Reg.
     2387).  Coastal means  "waters of the United States...located landward of
     the territorial seas".  Under these regulations, all such discharges were
     required to cease by January 1, 1997.

     3)  The Outer Continental Shelf ("OSC") permit covering oil and gas
     operations in federal waters in the Gulf (seaward of the Louisiana and
     Texas territorial seas) was reissued in November 1992 and modified in
     December 1993.  The existing permit was combined with a new source permit
     on August 9, 1996 (61 Fed. Reg. 41609).  This permit prohibits certain
     discharges of drilling fluids and drill cuttings and includes stricter
     limits for oil and grease concentrations in produced waters to be
     discharged.  These limits are based on the Best Available Treatment ("BAT")
     requirements contained in the Oil and Gas Offshore Subcategory national
     guidelines which were published March 3, 1993.  Additional requirements
     include toxicity testing and bioaccumulation monitoring studies of proposed
     discharges.  The combined permit expired on November 18, 1997; however, the
     expired permit will continue to be effective for permittees that applied
     for a new permit prior to the expiration date, until the EPA issues a new
     general permit for this area or requires permittees to seek individual
     permits.

     4)  A permit for the territorial seas of Louisiana was issued on November
     4, 1997 (62 Fed. Reg. 59687).  The permit becomes effective on December 4,
     1997, except for the water quality based limits and certain monitoring
     requirements that became effective May 4, 1998.  The permit prohibits the
     discharge of drilling fluids, drill cuttings and produced sand.  Produced
     water discharges are limited for oil and grease, toxic metals, organics,
     and chronic toxicity.  The territorial seas part of the Offshore
     Subcategory begins at the line of ordinary low water along the part of the
     coast which is in direct contact with the open sea, and extends out three
     nautical miles.  This permit covers both existing sources and new sources.
     All discharges in state waters must comply with any more stringent
     requirements contained in Louisiana Water Quality Regulations, LAC
     33.IX.7.708.  A similar permit will be proposed for the Texas territorial
     seas in the future.

     The combined effect of all these permits closely approaches a "zero
discharge standard" affecting all waters except those of the OCS.  Newpark and
many industry participants believe that these permits and the requirements of
the Clean Water Act may ultimately lead to a total prohibition of overboard
discharge in the Gulf of Mexico.

          The Clean Air Act.  The Clean Air Act provides for federal, state and
local regulation of emissions of air pollutants into the atmosphere.  Any
modification or construction of a facility with regulated air emissions must be
a permitted or authorized activity.  The Clean Air Act provides for
administrative and judicial enforcement against owners and operators of
regulated facilities, including substantial penalties. In 1990, the Clean Air
Act was reauthorized and amended, substantially increasing the scope and
stringency of the Clean Air Act's regulations.  The Clean Air Act has very
little impact on Newpark's operations.

          Oil Pollution Act of 1990.  The Oil Pollution Act of 1990 contains
liability provisions for cleanup costs, natural resource damages and property
damages resulting from discharges of oil into navigable waters, as well as
substantial penalty provisions.  The OPA also requires double hulls on all new
oil tankers and barges operating in waters subject to the jurisdiction of the
United States.  All marine vessels operated by Newpark already meet this
requirement.

          State Regulation.  In 1986, the Louisiana Department of Natural
Resources promulgated Order 29-B.  Order 29-B contains extensive rules governing
pit closure and the generation, treatment, storage, transportation and disposal
of NOW.  Under Order 29-B, onsite disposal of NOW is limited and is subject to
stringent guidelines.  If these guidelines cannot be met, NOW must be
transported and disposed of offsite in accordance with the provisions of Order
29-B.  Moreover, under Order 29-B, most, if not all, active waste pits must be
closed or modified to meet regulatory standards; those pits that continue to be
allowed may be used only for a limited time.  A material number of these pits
may contain concentrations of radium that are sufficient to require the waste
material to be categorized as NORM.

     Rule 8 of the Texas Railroad Commission also contains detailed requirements
for the management and disposal of NOW and Rule 94 governs the management and
disposal of NORM.  In addition, Rule 91 regulates the cleanup of spills of crude
oil from oil and gas exploration and production activities, including
transportation by pipeline.  In general, contaminated soils must be remediated
to total petroleum hydrocarbons content of less than 1%.  The State of Texas
also has established an Oilfield Cleanup Fund to be administered by the Texas
Railroad Commission to plug abandoned wells if the Commission deems it necessary
to prevent pollution, and to control or clean up certain oil and gas wastes that
cause or are likely to cause pollution of surface or subsurface water.  Other
states (New Mexico, Mississippi, Arkansas) where the Company operates have
similar regulations.  Oklahoma is presently in the process of drafting NORM oil
and gas regulations.  Newpark recently received the first specific license to do
NORM remediation in Arkansas.

     Many states maintain licensing and permitting procedures for the
construction and operation of facilities that emit pollutants into the air.  In
Texas, the Texas Natural Resource Conservation Commission (the "TNRCC") requires
companies that emit pollutants into the air to apply for an air permit or to
satisfy the conditions for an exemption.  Newpark has obtained certain air
permits and believes that it is exempt from obtaining other air permits at its
facilities including its Port Arthur, Texas, NOW facility.  Newpark met with the
TNRCC and filed for an exemption in the fall of 1991.  A subsequent renewal
letter was filed in 1995.  Based upon communications with the TNRCC, Newpark
expects that it will continue to remain exempt. However, should it not remain
exempt, Newpark believes that compliance with the permitting requirements of the
TNRCC would not have a material adverse effect on the consolidated financial
statements of Newpark.

          Other Environmental Laws.  Newpark is subject to the Occupation Safety
and Health Act that imposes requirements for employee safety and health and
applicable state provisions adopting worker health and safety requirements.
Moreover, it is possible that other developments, such as increasingly stricter
environmental, safety and health laws, and regulations and enforcement policies
thereunder, could result in substantial additional regulation of Newpark and
could subject to further scrutiny Newpark's handling, manufacture, use or
disposal of substances or pollutants.  Newpark cannot predict the extent to
which its operations may be affected by future enforcement policies as applied
to existing laws or by the enactment of new statutes and regulations.

RISK MANAGEMENT

     Newpark's business exposes it to substantial risks.  For example, Newpark's
environmental services routinely involve the handling, storage and disposal of
nonhazardous regulated materials and waste, and in some cases, handling of
hazardous regulated materials and waste for its customers which are generators
of such waste.  Newpark could be held liable for improper cleanup and disposal,
which liability could be based upon statute, negligence, strict liability,
contract or otherwise.  As is common in the oil and gas industry, Newpark often
is required to indemnify its customers or other third-parties against certain
risks related to the services performed by Newpark, including damages stemming
from environmental contamination.

     Newpark has implemented various procedures designed to ensure compliance
with applicable regulations and reduce the risk of damage or loss.  These
include specified handling procedures and guidelines for regulated waste,
ongoing training and monitoring of employees and maintenance of insurance
coverage.

     Newpark carries a broad range of insurance coverages that management
considers adequate for the protection of its assets and operations.  This
coverage includes general liability, comprehensive property damage, workers'
compensation and other coverage customary in its industries; however, this
insurance is subject to coverage limits and certain policies exclude coverage
for damages resulting from environmental contamination.  Newpark could be
materially adversely affected by a claim that is not covered or only partially
covered by insurance.  There is no assurance that insurance will continue to be
available to Newpark, that the possible types of liabilities that may be
incurred by Newpark will be covered by its insurance, that Newpark's insurance
carriers will meet their obligations or that the dollar amount of such
liabilities will not exceed Newpark's policy limits.

PROPERTIES

     Newpark's corporate offices in Metairie, Louisiana, are occupied at an
annual rental of approximately $125,000 under a lease expiring in December 2002.

     During 1996, Newpark acquired an office building in Lafayette, Louisiana,
to house the administrative offices of two of its subsidiaries.

     Newpark's Port Arthur, Texas, NOW and NORM facility is subject to annual
rentals aggregating approximately $500,000 under three separate leases.  A total
of 6.0 acres are under lease with various expiration dates from June 1997 to
September 2002, all with extended options to renew.

     Newpark owns two injection disposal sites in Jefferson County, Texas, one
on 50 acres of land and the other on 400 acres.  Eight wells are currently
operational at these sites.  In January 1997, Newpark completed the purchase of
120 acres located adjacent to one of the disposal sites.  Newpark plans to use
this property as an industrial waste injection disposal facility.  Newpark also
has acquired an additional injection facility, which includes two active
injection wells on 37 acres of land, adjacent to its Big Hill, Texas facility.

     In October 1997, Newpark acquired land and facilities in Andrews, Big
Springs, Plains and Fort Stockton, Texas at which brine is extracted and sold
and NOW is disposed of in the salt domes or caverns created by the extraction
process.  A total of 125 acres of land was acquired in this transaction.

     Newpark maintains a fleet of 43 barges, of which 19 are owned by Newpark,
10 are under 10-year lease terms, four are under seven-year lease terms and 10
are under five-year lease terms.  The barges are 

                                       58
<PAGE>
 
used to transport waste to processing stations and are certified for this
purpose by the U. S. Coast Guard. Annual rentals under the barge leases totaled
approximately $1.9 million during 1996.

     Additional facilities are held under short-term leases with annual rentals
aggregating approximately $725,000 during 1996.  Newpark believes that its
facilities are suitable for their respective uses and adequate for current
needs.

     Newpark also owns 80 acres occupied as a sawmill facility near Batson,
Texas.  Newpark believes this facility is adequate for current production needs.

LEGAL PROCEEDINGS

     Newpark and its subsidiaries are involved in litigation and other claims or
assessments on matters arising in the normal course of business.  In the opinion
of Newpark, any recovery or liability in these matters should not have a
material effect on Newpark's consolidated financial statements.

ENVIRONMENTAL PROCEEDINGS

     In the ordinary course of conducting its business, Newpark becomes involved
in judicial and administrative proceedings involving governmental authorities at
the federal, state and local levels, as well as private party actions.  Pending
proceedings that allege liability related to environmental matters are described
below.  Newpark believes that none of these matters involves material exposure.
There is no assurance, however, that such exposure does not exist or will not
arise in other matters relating to Newpark's past or present operations.

     Newpark was identified by the EPA as a minor or "de minimus" contributor of
waste to a disposal site requiring cleanup under CERCLA.  That facility, the
French Limited site, located in Southeast Texas, is currently undergoing a
voluntary cleanup by those parties identified as waste contributors.  Five
related private party suits have been filed against Newpark and the other
potentially responsible parties at the French Limited site.  Newpark has settled
its potential liability in four of those suits.  Management does not anticipate
that the outcome of the remaining suit will have a material adverse impact upon
Newpark, and anticipates either a nominal settlement or dismissal from the
action.

     Newpark has been identified as one of 600 contributors of material to the
MAR Services facility, a state voluntary cleanup site located in Louisiana.
Because Newpark delivered only processed solids meeting the requirements of
Louisiana Statewide Executive Order 29-B to the site, it does not believe it has
material financial liability for the site cleanup cost.  The DEQ is overseeing
voluntary cleanup at the site.

     Recourse against its insurers under general liability insurance policies
for reimbursement of cost and expense in the foregoing CERCLA actions is
uncertain as a result of conflicting court decisions in similar cases.  In
addition, certain insurance policies under which coverage may be afforded
contain self-insurance levels that may exceed Newpark's ultimate liability.

     Newpark believes that any liability incurred in the foregoing matters will
not have a material adverse effect on Newpark's consolidated financial
statements.

                   DESCRIPTION OF CERTAIN OTHER INDEBTEDNESS

     The following summary of certain agreements and instruments of the Company
does not purport to be complete and is qualified in its entirety by reference to
the various agreements and instruments described. Capitalized terms that are
used but not defined in this section have the meanings given such terms in their
respective agreement, unless the context otherwise requires.

     On June 30, 1997, Newpark, as borrower,  and the Guarantors, as guarantors,
entered into the Credit Facility with the lenders named therein (the "Lenders")
and Bank One, Louisiana, National Association as administrative and syndication
agent for the Lenders.

     The Credit Facility provides for a $90.0 million revolving credit facility
maturing on June 30, 2000, including up to $5.0 million in standby letters of
credit.  As of September 30, 1997, approximately $73.7 million was outstanding
under the Credit Facility, and there were approximately $2.0 million in
outstanding standby letters of credit.  The amounts borrowed under the Credit
Facility were used to refinance term debt, purchase drilling fluids assets,
expand mat inventories, acquire disposal assets and provide for working capital.
On November 7, 1997, the Credit Facility was amended to provide for a $10.0
million special advance note, due December 31, 1997, the proceeds of which were
used to fund the acquisition of certain assets of Anchor Drilling.  The special
advance note was treated as an additional advance under the Credit Facility.
Upon the completion of the 144A Notes Offering, Newpark repaid all amounts
outstanding under the Credit Facility, including the amounts outstanding under
the special advance note.

     Newpark's obligations under the Credit Facility have been guaranteed on a
joint and several basis by all of the Guarantors.  Borrowings under the Credit
Facility were originally secured by the accounts receivable, inventories,
equipment and general intangibles of Newpark located in Louisiana and Texas.
However, the Credit Facility was amended effective upon the closing of 144A
Notes Offering to release the security interests of the Lenders in such assets
and to permit the issuance of the 144A Notes.

     Advances under the Credit Facility bear interest at a variable rate equal
to, at Newpark's option,  (i) the Base Rate (defined as the rate established
from time to time by Agent) or (ii) the LIBOR rate plus a spread ranging from 1%
to 2% depending upon the ratio of Newpark's Consolidated Funded Debt to
Consolidated EBITDA.  Newpark is required to pay the Lenders under the Credit
Facility, on a quarterly basis, a commitment fee on the unused portion of the
Credit Facility ranging from 0.25% to 0.50% depending on the ratio of
Consolidated Funded Debt to Consolidated EBITDA, measured at the end of each
fiscal quarter and calculated on a trailing four quarter basis.  Newpark also
paid facility fees of $112,500 upon the establishment of the Credit Facility and
$25,000 upon the issuance of the special advance note, and will be required to
pay administration fees to the agent.

     The Credit Facility contains a number of covenants, including, among
others, covenants restricting Newpark and the Guarantors with respect to the
incurrence of indebtedness; the amendment of the Notes or the Guarantees; the
creation of liens; the sale, lease, assignment, transfer or other disposition of
assets, including any voting stock of any Guarantor; the making of certain
investments, loans or advances; the consummation of certain transactions, such
as mergers or consolidations; transactions with affiliates; and declaration of
dividends.  In addition, the Credit Facility contains affirmative covenants,
including among others, requirements regarding payment of taxes and other
obligations; compliance with laws; maintenance of insurance;  the keeping of
books and records; and environmental compliance.

     Newpark is also required to comply with certain financial tests and
maintain certain financial ratios, including, among others, (i) maintaining a
minimum ratio of Consolidated Current Assets to Consolidated 

                                       62
<PAGE>
 
Current Liabilities; (ii) maintaining a minimum ratio of Consolidated Adjusted
EBITDA to Consolidated Debt Service; (iii) preventing the ratio of total Debt
(including capitalized lease obligations, but excluding the Notes) to Total
Capitalization (including the Notes) from exceeding a specified percentage; (iv)
maintaining minimum levels of Consolidated Tangible Net Worth; and (v)
preventing the ratio of Consolidated Funded Debt to Consolidated EBITDA from
exceeding a specified percentage. The Credit Facility contains customary events
of default. An event of default under the Credit Facility would allow the
Lenders to accelerate or, in certain cases, would automatically cause the
acceleration of, the maturity of the indebtedness under the Credit Facility.
Such acceleration would restrict the ability of the Company to meet its
obligations with respect to the Exchange Notes.

                       DESCRIPTION OF THE EXCHANGE NOTES

     The Exchange Notes offered hereby will be issued, and the 144A Notes were
issued, under an Indenture dated as of December 17, 1997 (the "Indenture"),
among the Company, the Guarantors and State Street Bank & Trust Company, as
trustee (the "Trustee").  Reference to the Notes includes the Exchange Notes and
the 144A Notes.  Upon the effectiveness of the Registration Statement of which
this Prospectus is a part, the Indenture will be subject to and governed by the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

     The following summary of the material provisions of the Indenture does not
purport to be complete and is subject to, and qualified in its entirety by,
reference to the provisions of the Indenture, including the definitions of
certain terms contained therein and those terms made part of the Indenture by
reference to the Trust Indenture Act.  A copy of the Indenture is filed as an
exhibit to the Registration Statement of which this Prospectus is a part and is
incorporated by reference herein.  The definitions of certain capitalized terms
used in the following summary are set forth below under "--Certain Definitions."
All references to the Company in the following summary refer exclusively to
Newpark Resources, Inc., a Delaware corporation, and not to any of its
subsidiaries.

GENERAL

     The Exchange Notes will be issued solely in exchange for an equal principal
amount of 144A Notes pursuant to the Exchange Offer.  The form and terms of the
Exchange Notes will be identical in all material respects to the form and terms
of the 144A Notes except that the offering of the Exchange Notes has been
registered under the Securities Act, and the Exchange Notes will therefore not
be subject to transfer restrictions, registration rights and certain provisions
relating to an increase in the stated interest rate on the 144A Notes under
certain circumstances.  See "The Exchange Offer."

     The 144A Notes and the Exchange Notes will constitute a single series of
debt securities under the Indenture.  If the Exchange Offer is consummated,
holders of 144A Notes who do not exchange their 144A Notes for Exchange Notes
will vote together with holders of the Exchange Notes for all relevant purposes
under the Indenture.  In that regard, the Indenture requires that certain
actions by the holders thereunder (including acceleration following an Event of
Default) must be taken, and certain rights must be exercised, by specified
minimum percentages of the aggregate principal amount of the outstanding
securities issued under the Indenture.  In determining whether holders of the
requisite percentage in principal amount have given any notice, consent or
waiver or taken any other action permitted under the Indenture, any 144A Notes
that remain outstanding after the Exchange Offer will be aggregated with the
Exchange Notes, and the holders of such 144A Notes and the Exchange Notes will
vote together as a single series for all such purposes.  Accordingly, all
references herein to specified percentages in aggregate principal amount of the

                                       63
<PAGE>
 
outstanding Notes shall be deemed to mean, at any time after the Exchange Offer
is consummated, such percentages in aggregate principal amount of the 144A Notes
and the Exchange Notes then outstanding.

     The Notes are unsecured senior subordinated obligations of the Company
limited to $125,000,000 aggregate principal amount.  The obligations of the
Company under the Notes will be guaranteed on an unsecured senior subordinated
basis by the Guarantors.

MATURITY, INTEREST AND PRINCIPAL

     The Notes will mature on December 15, 2007.  Interest on the Notes will
accrue at the rate of 8 5/8% per annum and will be payable semi-annually on each
June 15 and December 15,  commencing  June 15, 1998, to the holders of record of
the Notes at the close of business on the June 1 and  December 1 immediately
preceding such interest payment date.  Interest on the Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the Issue Date.  Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

       Principal of, premium, if any, and interest on the Notes will be payable,
and the Notes will be transferable, at the corporate trust office or agency of
the Trustee in The City of New York maintained for such purposes.  In addition,
if the Notes do not remain in book-entry form, interest may be paid at the
option of the Company by check mailed to the person entitled thereto as shown on
the security register.  No service charge will be made for any transfer,
exchange or redemption of Notes, except in certain circumstances for any tax or
other governmental charge that may be imposed in connection therewith.

     The Notes are not subject to the benefit of any mandatory sinking fund.
However, upon the occurrence of certain Asset Sales or a Change of Control,
holders of Notes will have the right to require the Company to purchase their
Notes, as more fully described under "--Certain Covenants--Disposition of
Proceeds of Asset Sales" and "--Change of Control," respectively.

OPTIONAL REDEMPTION

     Optional Redemption.  The Notes will be redeemable at the option of the
Company, in whole or in part, at any time on or after December 15, 2002, at the
redemption prices (expressed as percentages of principal amount) set forth
below, plus accrued and unpaid interest, if any, to the redemption date, if
redeemed during the 12-month period beginning December 15 of the years indicated
below:
     
                                                  REDEMPTION
YEAR                                                 PRICE
- ----                                              ----------
2002............................................  104.313%
2003............................................  102.875%
2004............................................  101.438%
2005 and thereafter.............................  100.000%


     In addition, at any time and from time to time prior to or on December 1,
2000, the Company may redeem in the aggregate up to 35% of the original
principal amount of the Notes with the proceeds of one or more Public Equity
Offerings, at a redemption price (expressed as a percentage of principal amount)
of 108 5/8% plus accrued interest to the redemption date (subject to the right
of holders of record on the relevant record date to receive interest due on the
relevant interest payment date); provided, however, that at least $81.25 million
aggregate principal amount of Notes must remain outstanding after each such
redemption. Any such redemption must occur within 60 days following the closing
of such Public Equity Offering.

                                       64
<PAGE>
 
     Selection and Notice.  If less than all of the Notes are to be redeemed at
any time, selection of such Notes for redemption will be made by the Trustee in
compliance with any applicable requirements of the principal national securities
exchange, if any, on which the Notes are listed or, if the Notes are not then
listed on a national securities exchange (or if the Notes are so listed but such
exchange does not impose requirements with respect to the selection of debt
securities for redemption), on a pro rata basis, by lot or by such method as the
Trustee in its sole discretion shall deem fair and appropriate; provided,
however, that no Notes of a principal amount of $1,000 or less shall be redeemed
in part.  Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days before the redemption
date, to each holder of Notes to be redeemed, at its address as shown in the
security register.  If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed.  A new Note in a principal amount equal to the
unredeemed portion thereof will be issued in the name of the holder thereof upon
surrender for cancellation of the original Note.  On and after the redemption
date, interest will cease to accrue on Notes or portions thereof called for
redemption unless the Company defaults in the payment of the redemption price.

GUARANTEES

     All of the Company's subsidiaries on the date of the Indenture, other than
Mallard & Mallard, Inc., BFC Oil Company, JPI Acquisition Corp., Chessher
Construction, Inc., Consolidated Mayflower Mines, Inc., George R. Brown
Services, Inc., Florida Mat Rental, Inc., International Mat, Ltd., IML de
Venezuela, L.L.C. and SOLOCO FSC, Inc., have, jointly and severally, fully and
unconditionally guaranteed the Company's obligations under the Notes.  In
addition, the Indenture provides that if (i) any Restricted Subsidiary of the
Company (other than an Exempt Foreign Subsidiary), whether now existing or
hereafter formed or acquired, becomes a Significant Subsidiary or (ii) any
Restricted Subsidiary of the Company, whether now existing or hereafter formed
or acquired, becomes a guarantor, obligor or grantor in respect of any other
Indebtedness of the Company or any other Restricted Subsidiary or obligor on its
Indebtedness (as more fully described under "--Certain Covenants--Limitation on
Non-Guarantor Restricted Subsidiaries"), the Company shall cause such Restricted
Subsidiary to enter into a supplemental Indenture pursuant to which such
Restricted Subsidiary shall agree to guarantee the Company's obligations under
the Notes.  If the Company defaults in payment of the principal of, premium, if
any, or interest on the Notes, each of the Guarantors will be unconditionally,
jointly and severally obligated to duly and punctually pay the same.

     The obligations of each Guarantor under its Guarantee are limited to the
maximum amount which, after giving effect to all other contingent and fixed
liabilities of such Guarantor, and after giving effect to any collections from
or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guarantee or pursuant to its
contribution obligations under the Indenture, will result in the obligations of
such Guarantor under its Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under Federal or state law.  Each Guarantor that makes a
payment or distribution under its Guarantee shall be entitled to a contribution
from each other Guarantor in a pro rata amount based on the net assets of each
Guarantor determined in accordance with GAAP.  See "--Certain Covenants--
Limitation on Issuances of Guarantees of Indebtedness."

     Subject to the requirements described under "--Consolidation, Merger, Sale
of Assets, Etc.," any Guarantee by a Guarantor shall be automatically and
unconditionally released and discharged (i) upon any sale, exchange or transfer
to any person (other than an Affiliate of the Company) of all of the Capital
Stock of such Restricted Subsidiary, or all or substantially all of the assets
of such Restricted Subsidiary, pursuant to a transaction which is in compliance
with the Indenture (including, but not limited to, the covenant described in "--
Certain Covenants--Disposition of Proceeds of Asset Sales" below) and such
Restricted Subsidiary is released from all guarantees and other security, if
any, by it of other Indebtedness of the 

                                       65
<PAGE>
 
Company or any Restricted Subsidiaries or (ii) at the request of the Company, if
the lenders under the Credit Facility (or any other revolving credit or term
loan facility entitled to a guarantee from such Guarantor) unconditionally
release such Guarantor from its joint and several obligations under such
facility and such Restricted Subsidiary does not then guarantee, or secure with
a Lien on any of its assets or properties, any other Indebtedness of the Company
or any other Restricted Subsidiary, in each such event described in this clause
(ii), such release and discharge to be effective so long as and for such periods
that such Guarantor does not guarantee, or secure with a Lien on any of its
assets or properties, any Indebtedness of the Company or any other Restricted
Subsidiary. Provisions herein and in the Indenture that refer to a person as a
Restricted Subsidiary shall also be applicable to a Guarantor, unless otherwise
provided by the context; and provisions herein and in the Indenture that refer
to a Guarantor shall only be applicable to a Restricted Subsidiary so long as,
and during such periods that, such person constitutes a Guarantor when such
provisions are being applied. The Company may, at any time and from time to time
(including, without limitation, following a release of a Guarantee pursuant to
clause (ii) of this paragraph), cause a Restricted Subsidiary to become a
Guarantor by executing and delivering a supplemental indenture providing for the
guarantee of payment of the Notes by such Restricted Subsidiary on the basis
provided in the Indenture. See "--Certain Covenants--Limitation on Non-Guarantor
Restricted Subsidiaries."

     The Guarantees will be unsecured senior subordinated obligations of the
Guarantors and will be subordinated to all existing and future Guarantor Senior
Indebtedness, which includes indebtedness of the Guarantors as joint and several
obligors under the Credit Facility.  As of September 30, 1997, on an as adjusted
basis after giving effect to the sale of the 144A Notes and the application of
the net proceeds therefrom and the Credit Facility, the Guarantors would have
had outstanding approximately $4.4 million in aggregate principal amount of
Guarantor Senior Indebtedness which ranked senior in right of payment to the
Guarantees.

SUBORDINATION

     Payments of any distribution on or with respect to the Senior Subordinated
Obligations of the Company will be subordinated, to the extent set forth in the
Indenture, in right of payment to the prior payment in full in cash or cash
equivalents of all existing and future Senior Indebtedness which includes,
without limitation, Credit Facility Obligations of the Company.  The Exchange
Notes will rank prior in right of payment only to other indebtedness of the
Company which is, by its terms, expressly subordinated in right of payment to
the Exchange Notes, and the Exchange Notes will in all respects rank pari passu
with all other Senior Subordinated Obligations of the Company, including any
144A Notes that remain outstanding.  There is currently no indebtedness of the
Company which is, by its terms, expressly subordinated in right of payment to
the Notes, and there is currently no indebtedness of the Company which is pari
passu in right of payment with the Notes.  In addition, the Senior Subordinated
Obligations of the Company will be effectively subordinated to all of the
creditors of its subsidiaries, including trade creditors.  See "Risk Factors--
Holding Company Structure; Possible Invalidity of Guarantees; Potential Release
of Guarantees."

     The Indenture provides that in the event of (a) any insolvency or
bankruptcy case or proceeding, or any receivership, liquidation, reorganization
or other similar case or proceeding in connection therewith, relating to the
Company (or its creditors, as such) or its assets, or (b) any liquidation,
dissolution or other winding-up of the Company, whether voluntary or
involuntary, or (c) any assignment for the benefit of creditors or other
marshaling of assets or liabilities of the Company, all Senior Indebtedness must
be paid in full in cash or cash equivalents before any direct or indirect
payment or distribution, whether in cash, property or securities (excluding
certain permitted equity and subordinated debt securities referred to in the
Indenture as "Permitted Junior Securities"), is made on account of the Senior
Subordinated Obligations of the Company.  If, notwithstanding the foregoing, the
Trustee or the holder of any Note receives any payment 

                                       66
<PAGE>
 
or distribution of properties or assets of the Company of any kind or character,
whether in cash, property or securities, by set-off or otherwise, in respect of
Senior Subordinated Obligations of the Company before all Senior Indebtedness is
paid or provided for in full, then the Trustee or the holders of Notes receiving
any such payment or distribution (other than a payment or distribution forthwith
in the form of Permitted Junior Securities) will be required to pay or deliver
such payment or distribution to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other person making payment or
distribution of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full.

     During the continuance of any default in the payment when due (whether at
Stated Maturity, upon scheduled repayment, upon acceleration or otherwise) of
principal of or premium, if any, or interest on, or of unreimbursed amounts
under drawn letters of credit or fees relating to letters of credit
constituting, any Designated Senior Indebtedness (a "Payment Default"), no
direct or indirect payment or distribution by or on behalf of the Company or any
Subsidiary of any kind or character shall be made on account of the Senior
Subordinated Obligations of the Company unless and until such default has been
cured or waived or has ceased to exist or such Designated Senior Indebtedness
shall have been discharged or paid in full in cash or cash equivalents.

     In addition, during the continuance of any default other than a Payment
Default with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may then be accelerated (a "Non-payment Default"), after
receipt by the Trustee from the holders (or their representative) of such
Designated Senior Indebtedness of a written notice of such Non-payment Default,
no payment or distribution of any kind or character may be made by the Company
on account of the Senior Subordinated Obligations of the Company for the period
specified below (the "Payment Blockage Period").

     The Payment Blockage Period shall commence upon the receipt of a notice of
a Non-payment Default by the Trustee from the holders (or their representative)
of Designated Senior Indebtedness stating that such notice is a payment blockage
notice pursuant to the Indenture and shall end on the earliest to occur of the
following events:  (i) 179 days shall have elapsed since the receipt by the
Trustee of such notice; (ii) the date, as set forth in a written notice to the
Company or the Trustee from the holders (or their representative) of the
Designated Senior Indebtedness initiating such Payment Blockage Period, on which
such default is cured or waived or ceases to exist (provided that no other
Payment Default or Non-payment Default has occurred or is then continuing after
giving effect to such cure or waiver); (iii) the date on which such Designated
Senior Indebtedness is discharged or paid in full in cash or cash equivalents;
or (iv) the date, as set forth in a written notice to the Company or the Trustee
from the holders (or their representative) of the Designated Senior Indebtedness
initiating such Payment Blockage Period, on which such Payment Blockage Period
shall have been terminated by written notice to the Company or the Trustee from
the holders (or their representative) of Designated Senior Indebtedness
initiating such Payment Blockage Period, after which the Company, subject to the
subordination provisions set forth above and the existence of another Payment
Default, shall promptly resume making any and all required payments in respect
of the Notes, including any missed payments.  Only one Payment Blockage Period
with respect to the Notes may be commenced within any 360 consecutive day
period.  No Non-payment Default with respect to Designated Senior Indebtedness
that existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness initiating
such Payment Blockage Period will be, or can be, made the basis for the
commencement of a second Payment Blockage Period, whether or not within a period
of 360 consecutive days, unless such default has been cured or waived for a
period of not less than 90 consecutive days (it being acknowledged that any
subsequent action, or any breach of any financial covenant for a period
commencing after the date of commencement of such Payment Blockage Period, that,
in either case, would give rise to a Non-payment Default pursuant to any
provision 

                                       67
<PAGE>
 
under which a Non-payment Default previously existed or was continuing shall
constitute a new Non-payment Default for this purpose; provided that, in the
case of a breach of a particular financial covenant, the Company shall have been
in compliance for at least one full 90 consecutive day period commencing after
the date of commencement of such Payment Blockage Period). In no event will a
Payment Blockage Period extend beyond 179 days from the date of the receipt by
the Trustee of the notice, and there must be a 181 consecutive day period in any
360-day period during which no Payment Blockage Period is in effect. If,
notwithstanding the foregoing, the Company makes any payment or distribution to
the Trustee or the holder of any Note prohibited by the subordination provision
of the Indenture, then such payment or distribution will be required to be paid
over and delivered forthwith to the holders (or their representative) of
Designated Senior Indebtedness.

     If the Company fails to make any payment on the Notes when due or within
any applicable grace period, whether or not on account of the payment blockage
provisions referred to above, such failure would constitute an Event of Default
under the Indenture and would enable the holders of the Notes to accelerate the
maturity thereof.  See "--Events of Default."

     By reason of such subordination, in the event of liquidation, receivership,
organization or insolvency, creditors of the Company who are holders of Senior
Indebtedness may recover more, ratably, than the holders of the Notes, and funds
which would be otherwise payable to the holders of the Notes will be paid to the
holders of the Senior Indebtedness to the extent necessary to pay the Senior
Indebtedness in full, and the Company may be unable to meet its obligations in
full with respect to the Notes.  In addition, as described above, the Senior
Subordinated Obligations of the Company will be effectively subordinate to the
claims of creditors of the Company's subsidiaries including trade creditors.

     As of September 30, 1997, on an as adjusted basis after giving effect to
the sale of the 144A Notes and the application of the net proceeds therefrom,
the aggregate amount of outstanding Senior Indebtedness of the Company would
have been approximately $1.9 million (all of which would be guarantees of
Indebtedness of the Company's consolidated subsidiaries), in addition to certain
bid and performance bonds (or letters of credit in respect of bids or
performance obligations) outstanding ($2.0 million at September 30, 1997), and
the aggregate amount of Guarantor Senior Indebtedness (including Indebtedness
guaranteed by the Company) would have been approximately $4.4 million.  The
foregoing amounts do not include the undrawn portions under the Credit Facility
and up to $17.6 million of third party indebtedness guaranteed by the Company.
See "Capitalization," "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources" and
"Description of Certain Other Indebtedness."

     Although the Indenture contains limitations on the amount of additional
Indebtedness that the Company and the Restricted Subsidiaries may incur, the
amounts of such Indebtedness could be substantial and, in any case, such
indebtedness may be Senior Indebtedness of the Company or Indebtedness of
Subsidiaries (including an Unrestricted Subsidiary), to which the Notes will be
structurally subordinated. See "--Certain Covenants--Limitation on Additional
Indebtedness."  There is no indebtedness of the Company which is subordinated in
right of payment to the Notes, and there is no indebtedness of the Company which
is pari passu in right of payment with the Notes.

     Each Guarantee of a Guarantor will be an unsecured senior subordinated
obligation of such Guarantor, ranking pari passu with, or senior in right of
payment to, all other existing and future Indebtedness of such Guarantor that is
expressly subordinated to Guarantor Senior Indebtedness.  The Indebtedness
evidenced by the Guarantees is subordinated to Guarantor Senior Indebtedness to
the same extent as the Notes are subordinated to Senior Indebtedness, and during
any period when payment on the Notes is blocked by Designated Senior
Indebtedness, payment on the Guarantees will be similarly blocked.

CERTAIN COVENANTS

     The Indenture contains the following covenants, among others:

     Limitation on Additional Indebtedness.  The Indenture provides that the
Company will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee, or in any other
manner become liable, contingently or otherwise (in each case, to "incur") for
the payment of, any Indebtedness (including any Acquired Indebtedness); provided
that (i) the Company and each Guarantor is permitted to incur Indebtedness
(including Acquired Indebtedness) and (ii) a Restricted Subsidiary which is not
a Guarantor is permitted to incur Acquired Indebtedness if (y), immediately
after giving pro forma effect thereto, the Consolidated Fixed Charge Coverage
Ratio of the Company would be equal to or greater than 2.00:1 and (z) no Default
or Event of Default shall have occurred and be continuing at the time such
Indebtedness or Acquired Indebtedness, as the case may be, is incurred or would
occur as a result of such incurrence.

     Notwithstanding the foregoing, the Company (and, to the extent specifically
set forth below, the Guarantors) may incur each and all of the following
Indebtedness (including any Acquired Indebtedness):

          (i) (a)  Indebtedness of the Company or any Guarantor under the Credit
     Facility in an aggregate principal amount at any time outstanding not to
     exceed $100 million, and any fees, premiums, expenses (including costs of
     collection), indemnities and other similar amounts payable in connection
     with such Indebtedness; and (b) other Indebtedness of the Company or any
     Guarantor outstanding on the Issue Date (other than Indebtedness described
     in clause (i)(a), (ii) or (v) of this covenant);

          (ii) Indebtedness of the Company evidenced by the Notes and
     Indebtedness of each Guarantor under its Guarantee;

          (iii)  Interest Rate Protection Obligations of the Company or any
     Guarantor covering Indebtedness of the Company or any Guarantor incurred in
     the ordinary course of business and permitted to be incurred by the Company
     or any Guarantor, as the case may be, pursuant to the Indenture; provided
     that the notional principal amount of any such Interest Rate Protection
     Obligations does not exceed 100% of the principal amount of the
     Indebtedness to which such Interest Rate Protection Obligations expressly
     relates;

          (iv) Indebtedness of the Company or any of the Guarantors under
     Currency Agreement Obligations; provided that such Currency Agreement
     Obligations (a) do not increase the Indebtedness or other obligations of
     the Company and the Guarantors outstanding other than as a result of
     fluctuations in foreign currency exchange rates or by reason of fees,
     indemnities and compensation payable thereunder and (b) are entered into in
     the ordinary course of business for the purpose of limiting risks that
     arise in the ordinary course of business of the Company and the Guarantors;

          (v) Indebtedness of the Company owed to a Restricted Subsidiary and
     Indebtedness of a Guarantor owed to the Company or another Guarantor;
     provided that (a) any subsequent issuance or transfer of Capital Stock or
     any Designation that results in such Restricted Subsidiary or Guarantor (as
     the case may be) ceasing to be a Restricted Subsidiary or any subsequent
     transfer, pledge or assignment of such Indebtedness (other than to the
     Company or another Guarantor) will be deemed to constitute the incurrence
     of such Indebtedness by the Company or such Guarantor, as 

                                       69
<PAGE>
 
     the case may be, not permitted by this clause (v) and (b) any such
     Indebtedness of the Company owed to a Restricted Subsidiary and any such
     Indebtedness of a Guarantor owed to another Guarantor, must be unsecured
     and subordinated in right of payment to the prior payment in full and
     performance of the Company's obligations under the Indenture and the Notes,
     and such Guarantor's obligations under its Guarantee, as the case may be;

          (vi) Indebtedness of the Company or any Guarantor incurred in respect
     of bid, performance and payment bonds (other than in respect of
     Indebtedness), surety bonds, trade letters of credit, bankers' acceptances
     and letters of credit supporting bids, advance payments and performance
     obligations of the Company or any Guarantor (other than in respect of
     Indebtedness), in each case incurred in the ordinary course of business;

          (vii)  Indebtedness of the Company or any Guarantor (a) representing
     Capitalized Lease Obligations or (b) Purchase Money Obligations for
     property acquired in the ordinary course of business, which taken together
     do not exceed $20 million in aggregate amount at any time outstanding;

          (viii)  Indebtedness of the Company or any Guarantor to the extent the
     proceeds thereof are used to Refinance Indebtedness of the Company
     (including all or a portion of the Notes) or any Guarantor to the extent
     the Indebtedness to be Refinanced, has been incurred under or referred to
     in the first paragraph of this covenant or clauses (i)(b), (ii), (vii)(b)
     or (ix); provided that the principal amount of Indebtedness incurred
     pursuant to this clause (viii) (or, if such Indebtedness provides for an
     amount less than the principal amount thereof to be due and payable upon a
     declaration of acceleration of the maturity thereof, the original issue
     price of such Indebtedness) shall not exceed the sum of the principal
     amount of Indebtedness so Refinanced (or, if such Indebtedness provides for
     an amount less than the principal amount thereof to be due and payable upon
     a declaration of acceleration of the maturity thereof, the original issue
     price of such Indebtedness plus any accredited value attributable thereto
     since the original issuance of such Indebtedness) plus the amount of any
     premium required to be paid in connection therewith pursuant to the terms
     of such Indebtedness or the amount of any premium reasonably determined by
     the Company or a Guarantor, as applicable, as necessary to accomplish the
     foregoing by means of a tender or exchange offer or privately negotiated
     purchase, plus the amount of expenses in connection therewith; and

          (ix) Indebtedness of the Company and the Guarantors (which may include
     any Indebtedness incurred for any purpose, including but not limited to the
     purposes referred to in clauses (i) through (viii) above) in an aggregate
     amount which, together with the amount of all other Indebtedness of the
     Company and the Guarantors outstanding on the date of such incurrence
     (other than Indebtedness permitted by clauses (i) through (viii) above or
     the initial paragraph of this covenant) does not exceed $25 million.

     Notwithstanding the immediately preceding paragraph of this covenant, the
Indenture provides that neither the Company nor any Guarantor shall incur any
Indebtedness pursuant to such immediately preceding paragraph of this covenant
if the proceeds thereof are used, directly or indirectly, (i) to Refinance any
Subordinated Obligations of the Company or such Guarantor, as the case may be,
unless such Indebtedness (A) shall be subordinated to the Notes or the relevant
Guarantee to at least the same extent as such Subordinated Obligations, (B) has
an Average Life to Stated Maturity greater than the lesser of (y) the remaining
Average Life to Stated Maturity of the Subordinated Obligations being Refinanced
or (z) the remaining Average Life to Stated Maturity of the Notes, and (C) has a
Stated Maturity for its final scheduled 

                                       70
<PAGE>
 
principal payment later than the Stated Maturity for the final scheduled
principal payment of the Subordinated Obligations being Refinanced, or (ii) to
Refinance any Pari Passu Indebtedness, unless such Refinancing does not reduce
the Average Life to Stated Maturity or the Stated Maturity of such Pari Passu
Indebtedness.

     Limitation on Restricted Payments.  The Indenture provides that the Company
will not, and will not permit any of the Restricted Subsidiaries to, directly or
indirectly:

           (i) declare or pay any dividend or make any other distribution or
     payment on or in respect of Capital Stock of the Company or any Restricted
     Subsidiary or any payment made to the direct or indirect holders (in their
     capacities as such) of Capital Stock of the Company or any Restricted
     Subsidiary (other than dividends or distributions payable solely (a) in
     Capital Stock of the Company (other than Redeemable Capital Stock), (b) in
     rights to purchase Capital Stock of the Company (other than Redeemable
     Capital Stock) and (c) to the Company);

          (ii) purchase, redeem, defease or otherwise acquire or retire for
     value any Capital Stock of the Company or any Restricted Subsidiary (other
     than any such Capital Stock owned by a Wholly-Owned Restricted Subsidiary);

          (iii)  make any principal payment on, or purchase, defease,
     repurchase, redeem or otherwise acquire or retire for value, prior to any
     scheduled maturity, scheduled repayment, scheduled sinking fund payment or
     other Stated Maturity, any Subordinated Obligations (other than any such
     Subordinated Obligations owed to a Wholly-Owned Restricted Subsidiary); or

          (iv) make any Investment (other than a Permitted Investment) in any
     person

(such payments or Investments described in (but not excluded from) the preceding
clauses (i) (other than by reason of the proviso thereto), (ii), (iii) and (iv)
are collectively referred to as "Restricted Payments"), unless, at the time of
and after giving effect to the proposed Restricted Payment (the amount of any
such Restricted Payment, if other than in cash, shall be the Fair Market Value
of the asset(s) proposed to be transferred by the Company or such Restricted
Subsidiary, as the case may be, pursuant to such Restricted Payment), (A) no
Default shall have occurred and be continuing, (B) the aggregate amount of such
Restricted Payment and all other Restricted Payments declared or made from and
after the Issue Date would not exceed the sum of (1) 50% of the aggregate
Consolidated Net Income of the Company accrued on a cumulative basis during the
period (treated as one accounting period) beginning on the Issue Date and ending
on the last day of the fiscal quarter of the Company immediately preceding the
date of such proposed Restricted Payment (or, if such aggregate cumulative
Consolidated Net Income of the Company for such period shall be a deficit, minus
100% of such deficit) plus (2) the aggregate net cash proceeds received by the
Company either (x) as capital contributions in the form of common equity to the
Company after the Issue Date or (y) from the issuance or sale of Capital Stock
(excluding Redeemable Capital Stock but including Capital Stock issued upon the
conversion of convertible Indebtedness, in exchange for outstanding Indebtedness
or from the exercise of options, warrants or rights to purchase Capital Stock
(other than Redeemable Capital Stock)) of the Company to any person (other than
to a Restricted Subsidiary or to an employee stock ownership plan or to a trust
established by the Company or any of its Subsidiaries for the benefit of their
employees) after the Issue Date plus (3) the aggregate net cash proceeds
received by the Company from the issuance or sale subsequent to the Issue Date
of its Capital Stock (other than Redeemable Capital Stock) to an employee stock
ownership or stock purchase plan, provided, however, that if such employee stock
ownership or stock purchase plan incurs any Indebtedness with respect thereto,
such aggregate amount shall be limited to an amount equal to any increase in the
consolidated net worth of the Company resulting from principal 

                                       71
<PAGE>
 
repayments made by such employee stock ownership or stock purchase plan with
respect to such Indebtedness plus (4) in the case of the disposition or
repayment of any Investment constituting a Restricted Payment made after the
Issue Date (excluding any Investment made pursuant to clause (iv) of the
following paragraph), an amount equal to the lesser of the return of capital
with respect to such investment and the initial amount of such Investment, in
either case, less the cost of the disposition of such Investment plus (5) 100%
of the aggregate amount of all Investments previously made on or after the date
of the Indenture in any Unrestricted Subsidiary upon the revocation of the
designation of such Unrestricted Subsidiary as such, other than Investments made
in such Unrestricted Subsidiary pursuant to clause (iv) of the following
paragraph and (C) the Company could incur $1.00 of additional Indebtedness under
the first paragraph of the "Limitation on Additional Indebtedness" covenant
described above. For purposes of the preceding clause (B)(2), upon the issuance
of Capital Stock either from the conversion of convertible Indebtedness or in
exchange for outstanding Indebtedness or upon the exercise of options, warrants
or rights, the amount counted as net cash proceeds received will be the cash
amount received by the Company at the original issuance of the Indebtedness that
is so converted or exchanged or from the issuance of options, warrants or
rights, as the case may be, plus the incremental amount of cash received by the
Company, if any, upon the conversion, exchange or exercise thereof.

     None of the foregoing provisions will prohibit (i) the payment of any
dividend within 60 days after the date of its declaration, if at the date of
declaration such payment would be permitted by the foregoing paragraph;
provided, however, that at the time of payment of such dividend, no other
Default shall have occurred and be continuing (or result therefrom); (ii) the
redemption, repurchase or other acquisition or retirement of any shares of any
class of Capital Stock of the Company or any Restricted Subsidiary in exchange
for, or out of the net cash proceeds of, a substantially concurrent issue and
sale of other shares of Capital Stock (other than Redeemable Capital Stock) of
the Company to any person (other than to a Restricted Subsidiary or an employee
stock ownership plan or to a trust established by the Company or any of its
Subsidiaries for the benefit of their employees); provided that such net cash
proceeds are excluded from clause (B)(2)(y) of the preceding paragraph; (iii) so
long as no Default shall have occurred and be continuing, any redemption,
repurchase or other acquisition or retirement of Subordinated Obligations by
exchange for, or out of the net cash proceeds of, a substantially concurrent
issue and sale of (1) Capital Stock (other than Redeemable Capital Stock) of the
Company to any person (other than to a Restricted Subsidiary or an employee
stock ownership plan or to a trust established by the Company or any of its
Subsidiaries for the benefit of their employees); provided that any such net
cash proceeds are excluded from clause (B)(2)(y) of the preceding paragraph; or
(2) Indebtedness of the Company so long as such Indebtedness (x) is subordinated
to the Notes in the same manner and at least to the same extent as the
Subordinated Obligations being redeemed, repurchased, acquired or retired, (y)
has no Stated Maturity earlier than the 91st day after the Stated Maturity for
the final scheduled principal payment of the Notes and (z) is permitted to be
incurred pursuant to the "Limitation on Additional Indebtedness" covenant
described above; and (iv) the making of Investments constituting Restricted
Payments made after the Issue Date as a result of the receipt of non-cash
consideration from any Asset Sale made pursuant to and in compliance with the
covenant "--Disposition of Proceeds of Asset Sales."  In computing the amount of
Restricted Payments previously made for purposes of clause (B) of the preceding
paragraph, Restricted Payments made under the immediately preceding clauses (i)
and (iv) shall be included.

     Limitation on Liens.  (a) The Indenture provides that the Company will not,
and will not permit any Restricted Subsidiary to, directly or indirectly,
create, incur, assume or suffer to exist any Lien of any kind against or upon
any of the Company's or such Restricted Subsidiary's (as the case may be)
property or assets, whether now owned or acquired after the date of the
Indenture, or any proceeds therefrom, which secures either (i) Subordinated
Obligations (other than Subordinated Obligations of a Restricted Subsidiary
owing to the Company secured by assets of such Restricted Subsidiary), unless
the Notes or Guarantees, as the case 

                                       72
<PAGE>
 
may be, are secured by a Lien on such property, assets or proceeds that is
senior in priority to the Liens securing such Subordinated Obligations or (ii)
Pari Passu Indebtedness unless the Notes or Guarantees, as the case may be, are
equally and ratably secured with the Liens securing such Pari Passu
Indebtedness. The foregoing covenant will not apply to any Lien securing
Acquired Indebtedness, provided that any such Lien extends only to the
properties or assets that were subject to such Lien prior to the related
acquisition by the Company or such Restricted Subsidiary and was not created,
incurred or assumed in contemplation of such transaction.

     (b) Notwithstanding the foregoing, any Lien granted by the Company or any
Restricted Subsidiary to secure the Notes or Guarantees, as the case may be,
created pursuant to paragraph (a) above shall provide by its terms that such
Lien shall be automatically and unconditionally released and discharged upon the
release by the holders of the Indebtedness of the Company or any Restricted
Subsidiary described in paragraph (a) above of their Lien (including any deemed
release upon payment in full of all obligations under such Indebtedness), at a
time when (A) no other Pari Passu Indebtedness and Subordinated Obligations of
the Company or any Restricted Subsidiary has been secured by such property or
assets of the Company or any such Restricted Subsidiary or (B) the holders of
all such other Pari Passu Indebtedness and Subordinated Obligations which is
secured by such property or assets of the Company or any such Restricted
Subsidiary also release their Lien in such property or assets (including any
deemed release upon payment in full of all obligations under such Indebtedness).

     Change of Control.  The Indenture provides that, upon the occurrence of a
Change of Control, the Company shall be obligated to make an offer to purchase
(a "Change of Control Offer") and shall, subject to the provisions described
below, purchase, on a business day not more than 60 nor less than 30 days
following the occurrence of the Change of Control, all of the then outstanding
Notes at a purchase price equal to 101% of the principal amount thereof plus
accrued and unpaid interest, if any (the "Change of Control Purchase Price"), to
the Change of Control Purchase Date.  The Company shall, subject to the
provisions described below, be required to purchase all Notes properly tendered
into the Change of Control Offer and not withdrawn.  The Change of Control Offer
is required to remain open for at least 20 business days and until the close of
business on the Change of Control Purchase Date.

     In order to effect such Change of Control Offer, the Company shall, not
later than the 30th day after the Change of Control, mail to each holder of
Notes notice of the Change of Control Offer, which notice shall govern the terms
of the Change of Control Offer and shall state, among other things, the
procedures that holders of Notes must follow to accept the Change of Control
Offer.

     If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by holders of Notes
seeking to accept the Change of Control Offer.  Instruments governing Senior
Indebtedness may prohibit the Company from purchasing any Notes prior to their
Stated Maturity, including pursuant to a Change of Control Offer.  If a Change
of Control occurs at a time when the Company does not have available funds
sufficient to pay the Change of Control Purchase Price or at a time when the
Company is prohibited from purchasing the Notes (and the Company is unable to
obtain the consent of such holders of Senior Indebtedness or to repay such
Senior Indebtedness), an Event of Default would occur under the Indenture.  The
definition of Change of Control includes an event by which the Company sells,
conveys, transfers or leases all or substantially all of its Properties to any
Person; the phrase "all or substantially all" is subject to applicable legal
precedent and as a result in the future there may be uncertainty as to whether a
Change of Control has occurred.  The Company shall not be required to make a
Change of Control Offer upon a Change of Control if a third party makes the
Change of Control Offer at the Change of Control Purchase Price, at the same
times and otherwise in compliance with the requirements applicable to a Change

                                       73
<PAGE>
 
of Control Offer made by the Company and purchases all Notes validly tendered
and not withdrawn under such Change of Control Offer.

     The occurrence of the events constituting a Change of Control under the
Indenture will result in an event of default under the Credit Facility as
presently in effect and, thereafter, the lenders will have the right to require
repayment of the borrowings thereunder in full.  The Credit Facility as
presently in effect does not permit the purchase of the Notes absent consent of
the lenders thereunder in the event of a Change of Control.

     The Company will comply with Section 14(e) and Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable, if a Change of Control occurs
and the Company is required to purchase Notes as described above.

     Disposition of Proceeds of Asset Sales.  The Indenture provides that the
Company will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, make any Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the shares,
properties or assets sold or otherwise disposed of, and (ii) with respect to any
Asset Sale for which the consideration exceeds $5 million, at least 75% of such
consideration consists of cash and/or Cash Equivalents (with Indebtedness of the
Company or any Restricted Subsidiary (other than any Restricted Subsidiary that
will cease to be a Restricted Subsidiary as a result of such Asset Sale) being
counted as cash for all purposes of this covenant if the Company or the
Restricted Subsidiary is unconditionally released from any liability therefor).
Net Cash Proceeds of any Asset Sale may be applied to repay Specified
Indebtedness or Credit Facility Obligations (but only if the commitments or
amounts available to be borrowed under such Specified Indebtedness or the Credit
Facility, as the case may be, are permanently reduced by the amount of such
payment).  To the extent that such Net Cash Proceeds are not applied as provided
in the preceding sentence, the Company or a Restricted Subsidiary, as the case
may be, may apply the Net Cash Proceeds from such Asset Sale, within 360 days of
the date of such Asset Sale, to an investment in properties and assets that were
the subject of such Asset Sale or in properties and assets that are similar to
the properties and assets that will be used in the business of the Company and
the Restricted Subsidiaries existing on the Issue Date or in businesses
reasonably related thereto ("Replacement Assets").  Any Net Cash Proceeds from
any Asset Sale not applied as provided in the preceding two sentences, within
360 days of the date of such Asset Sale, constitute "Excess Proceeds" subject to
disposition as provided below.

     When the aggregate amount of Excess Proceeds equals or exceeds $10 million,
the Company shall make an offer to purchase, from all holders of the Notes and
any then outstanding Pari Passu Indebtedness required to be repurchased or
repaid on a permanent basis in connection with an Asset Sale, an aggregate
principal amount of Notes and any such Pari Passu Indebtedness equal to such
Excess Proceeds as follows:

         (i) (a)  The Company shall make an offer to purchase (a "Net Proceeds
     Offer") from all holders of the Notes in accordance with the procedures set
     forth in the Indenture the maximum principal amount (expressed as a
     multiple of $1,000) of Notes that may be purchased out of an amount (the
     "Payment Amount") equal to the product of such Excess Proceeds multiplied
     by a fraction, the numerator of which is the outstanding principal amount
     of the Notes and the denominator of which is the sum of the outstanding
     principal amount of the Notes and such Pari Passu Indebtedness, if any
     (subject to proration if such amount is less than the aggregate Offered
     Price (as defined in clause (ii) below) of all Notes tendered), and (b) to
     the extent required by any such Pari Passu Indebtedness and provided there
     is a permanent reduction in the principal amount of such Pari Passu
     Indebtedness, the Company shall make an offer to purchase such Pari Passu
     Indebtedness (a "Pari Passu Offer") 

                                       74
<PAGE>
 
     in an amount (the "Pari Passu Indebtedness Amount") equal to the excess of
     the Excess Proceeds over the Payment Amount.

         (ii) The offer price for the Notes shall be payable in cash in an
     amount equal to 100% of the principal amount of the Notes tendered pursuant
     to a Net Proceeds Offer, plus accrued and unpaid interest, if any, to the
     date such Net Proceeds Offer is consummated (the "Offered Price"), in
     accordance with the procedures set forth in the Indenture.  To the extent
     that the aggregate Offered Price of the Notes tendered pursuant to a Net
     Proceeds Offer is less than the Payment Amount relating thereto or the
     aggregate amount of the Pari Passu Indebtedness that is purchased or repaid
     pursuant to the Pari Passu Offer is less than the Pari Passu Indebtedness
     Amount (such shortfall constituting a "Net Proceeds Deficiency"), the
     Company may use such Net Proceeds Deficiency, or a portion thereof, for
     general corporate purposes, subject to the limitations of the "Limitation
     on Restricted Payments" covenant.

         (iii)  If the aggregate Offered Price of Notes validly tendered and not
     withdrawn by holders thereof exceeds the Payment Amount, Notes to be
     purchased will be selected on a pro rata basis. Upon completion of such Net
     Proceeds Offer and Pari Passu Offer, the amount of Excess Proceeds shall be
     reset to zero.

     The Company will comply with Section 14(e) and Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable, if an Asset Sale occurs and the
Company is required to purchase Notes as described above.

     Limitation on Sale, Issuance and Ownership of Capital Stock of Restricted
Subsidiaries.  The Indenture provides that the Company (i) will not, directly or
indirectly, sell or otherwise dispose of any shares of Capital Stock of a
Restricted Subsidiary, (ii) will not permit any of the Restricted Subsidiaries,
directly or indirectly, to issue or sell or otherwise dispose of any Capital
Stock (other than (A) to the Company or a Wholly-Owned Restricted Subsidiary or
(B) to the extent such shares represent directors' qualifying shares or shares
required by applicable law to be held by a person other than the Company or a
Wholly-Owned Subsidiary), (iii) will not permit any person (other than the
Company or a Wholly-Owned Restricted Subsidiary), directly or indirectly, to own
any Capital Stock of any Restricted Subsidiary except for Capital Stock of a
Restricted Subsidiary issued and outstanding at the time such Restricted
Subsidiary became a Subsidiary of the Company; provided that such Capital Stock
was not issued in anticipation of such person becoming a Subsidiary of the
Company and (iv) will not permit any person, directly or indirectly, to acquire
Capital Stock of any Restricted Subsidiary from the Company or any Wholly-Owned
Restricted Subsidiary except upon the acquisition of all the outstanding Capital
Stock of such Restricted Subsidiary in accordance with the terms of the
Indenture.

     Limitation on Transactions with Affiliates.  The Indenture provides that
the Company will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, enter into or suffer to exist any transaction or series
of related transactions (including, without limitation, the sale, transfer,
disposition, purchase, exchange or lease of assets, property or services,
employee compensation arrangements or the rendering of any service) with, or for
the benefit of, any Affiliate of the Company (other than a Wholly-Owned
Restricted Subsidiary) except (i) on terms that are no less favorable to the
Company or the Restricted Subsidiary, as the case may be, than those which could
have been obtained in a comparable transaction at such time from persons who do
not have such a relationship with the Company, (ii) with respect to any
transaction or series of related transactions involving aggregate payments or
value equal to or greater than $2 million, the terms of such transaction or
transactions, as the case may be, shall be set forth in writing and the Company
shall have delivered an officer's certificate to the Trustee certifying that
such transaction or 

                                       75
<PAGE>
 
series of related transactions comply with the preceding clause (i), and (iii)
with respect to any transaction or series of related transactions involving
aggregate payments or value equal to or greater than $5 million, the terms of
such transaction or transactions, as the case may be, shall be set forth in
writing and the Company shall have delivered an officer's certificate to the
Trustee certifying that such transaction or series of transactions (A) comply
with the preceding clause (i) and (B) have been approved by a majority of the
Board of Directors of the Company, including a majority of the disinterested
directors of the Board of Directors of the Company, or in lieu of the
certification required by the preceding clause (B), the Company shall have
delivered to the Trustee a written opinion of an investment banking firm of
national standing or other recognized independent expert with experience
appraising the terms and conditions of the type of transaction or series of
related transactions for which its opinion is being delivered stating that the
transaction or series of related transactions is fair to the Company or such
Restricted Subsidiary from a financial point of view. For the purposes of the
foregoing, a director of the Company shall not be considered "interested" with
respect to a transaction solely by virtue of being a director of the other party
to such transaction. This covenant will not restrict the Company from (a) making
dividends permitted by the covenant "--Limitation on Restricted Payments," (b)
paying reasonable and customary regular fees to directors of the Company who are
not employees of the Company, (c) making loans or advances to officers of the
Company and the Restricted Subsidiaries in the ordinary course of business for
bona fide business purposes of the Company in an aggregate principal amount not
to exceed $1 million outstanding at any one time and (d) the Company's employee
compensation and other benefit arrangements existing on the Issue Date or
thereafter entered into by the Company or any Restricted Subsidiary in the
ordinary course of business.

     Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries.  The Indenture provides that the Company will not, and will not
permit any of the Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary to (a)
pay dividends, in cash or otherwise, or make any other distributions on or in
respect of its Capital Stock or any other interest or participation in, or
measured by, its profits, (b) pay any Indebtedness owed to the Company or any
other Restricted Subsidiary, (c) make loans or advances to the Company or any
other Restricted Subsidiary or (d) transfer any of its properties or assets to
the Company or any other Restricted Subsidiary (other than any customary
restriction on transfers of property subject to a Lien permitted under the
Indenture (other than a Lien on cash not constituting proceeds of non-cash
property subject to a Lien permitted under the Indenture)), except for such
encumbrances or restrictions existing under or by reason of (i) the mandatory
provisions of general applicability of applicable law or governmental
regulation, (ii) customary non-assignment provisions of any contract or any
licensing agreement entered into by the Company or any of the Restricted
Subsidiaries in the ordinary course of business or any lease governing a
leasehold interest of the Company or any Restricted Subsidiary, (iii) any
agreement or other instrument of a person acquired by the Company or any
Restricted Subsidiary in existence at the time of such acquisition (but not
created in contemplation thereof), which encumbrance or restriction is not
applicable to any person, or the properties or assets of any person, other than
the person, or the property or assets (including subsequently acquired property
or assets to the extent subject thereto) of the person, so acquired, (iv) any
encumbrance or restriction in the Credit Facility or any other agreement, in
each case, as in effect on the Issue Date, or otherwise modified from time to
time; provided that any such modification is no less favorable to the holders of
Notes (as determined by the Board of Directors of the Company) than the
applicable provision as in effect on the Issue Date and (v) any encumbrance or
restriction pursuant to any agreement that extends, restructures, refinances,
renews, refunds or replaces any agreement described in clause (ii), (iii) or
(iv) above, which is no less favorable to the holders of Notes (as determined by
the Board of Directors of the Company) than those existing under the agreement
being extended, restructured, refinanced, renewed, refunded or replaced.

                                       76

     Limitation on Certain Senior Subordinated Obligations.  The Indenture
provides that the Company will not, and will not permit any Guarantor or
Restricted Subsidiary which is not a Guarantor to, directly or indirectly,
create, incur, issue, assume, guarantee or otherwise in any manner become
directly or indirectly liable for or with respect to or otherwise permit to
exist any Indebtedness which is expressly subordinate or junior in right of
payment in any respect to any Indebtedness of the Company or such Guarantor or
Restricted Subsidiary which is not a Guarantor, as the case may be, unless such
Indebtedness ranks pari passu in right of payment with the Notes or the
Guarantee of such Guarantor, or is expressly subordinated in right of payment to
the Notes or such Guarantee at least to the same extent as the Notes or such
Guarantee are subordinate in right of payment to Senior Indebtedness or
Guarantor Senior Indebtedness, as the case may be.

     Limitation on Designation of Unrestricted Subsidiaries.  The Indenture
provides that the Company may, pursuant to resolution of its Board of Directors,
designate any Subsidiary of the Company as an "Unrestricted Subsidiary" under
the Indenture (a "Designation") only if:

         (i) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Designation;

         (ii) the Company would be permitted under the Indenture to make an
     Investment at the time of Designation (assuming the effectiveness of such
     Designation) in an amount (the "Designation Amount") equal to the Fair
     Market Value of the Capital Stock of such Subsidiary on such date;

         (iii)  the Company would be permitted under the Indenture to incur
     $1.00 of additional Indebtedness pursuant to the first paragraph of the
     covenant described under "--Limitation on Additional Indebtedness" at the
     time of Designation (assuming the effectiveness of such Designation);

         (iv) with respect to the Subsidiary to be designated an Unrestricted
     Subsidiary, each of the Company and its Subsidiaries, other than the
     Subsidiary to be designated an Unrestricted Subsidiary, is in compliance
     with the provisions of clauses (x), (y) and (z) of the next following
     paragraph, as if such Subsidiary to be so designated had been and is an
     Unrestricted Subsidiary for all purposes of such clauses, at the time of,
     and after giving effect to, such Designation (assuming the effectiveness of
     such Designation); and

         (v) the Subsidiary to be designated an Unrestricted Subsidiary, or any
     Subsidiary thereof, owns no Capital Stock or Indebtedness of, owes no
     Indebtedness to, or holds no Lien on any property of, the Company or any
     other Subsidiary of the Company that is not a Subsidiary of the Subsidiary
     to be so designated at the time of or after giving effect to such
     Designation (assuming the effectiveness of such Designation).

     In the event of any such Designation, the Company shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant "-
- -Limitation on Restricted Payments" for all purposes of the Indenture in the
Designation Amount.  The Indenture further provides that the Company shall not
and shall not permit any Restricted Subsidiary to, directly or indirectly, at
any time (x) provide credit support for, or a guarantee of, any Indebtedness of
any Unrestricted Subsidiary (including any undertaking, agreement or instrument
evidencing such Indebtedness), (y) be directly or indirectly liable for any
Indebtedness of an Unrestricted Subsidiary or (z) be directly or indirectly
liable for any Indebtedness which provides that the holder thereof may (upon
notice, lapse of time or both) declare a default thereon or cause the payment
thereof to be accelerated or payable prior to its final scheduled maturity upon
the occurrence 

                                       77
<PAGE>
 
of a default with respect to any Indebtedness of any Unrestricted Subsidiary
(including any right to take enforcement action against such Unrestricted
Subsidiary), except in the case of clause (x) or (y) to the extent permitted
under the covenant described under "--Limitation on Restricted Payments."

     The Indenture further provides that the Company may revoke any Designation
of a Subsidiary as an Unrestricted Subsidiary (a "Revocation") if:

         (i) no Default shall have occurred and be continuing at the time of and
     after giving effect to such Revocation; and

         (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately following such Revocation would, if incurred at
     such time, have been permitted to be incurred for all purposes of the
     Indenture.

     All Designations and Revocations must be evidenced by Board Resolutions of
the Company delivered to the Trustee certifying compliance with the foregoing
provisions.

     Limitation on Non-Guarantor Restricted Subsidiaries.

         (i) The Indenture provides that the Company will not permit any
Restricted Subsidiary, other than the Guarantors, directly or indirectly, to
secure the payment of any Senior Indebtedness, and the Company will not, and
will not permit any Restricted Subsidiary to, pledge any intercompany notes
representing obligations of any Restricted Subsidiary (other than the
Guarantors) to secure the payment of any Senior Indebtedness, unless in each
case such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a guarantee of payment of
the Notes by such Restricted Subsidiary, which guarantee shall be on the same
terms as the guarantee of the Senior Indebtedness (if a guarantee of Senior
Indebtedness is granted by any such Restricted Subsidiary) except that the
guarantee of the Notes need not be secured and shall be subordinated to the
claims against such Restricted Subsidiary in respect of Senior Indebtedness to
the same extent as the Notes are subordinated to Senior Indebtedness under the
Indenture.

         (ii) The Indenture further provides that the Company will not permit
any Restricted Subsidiary which is not a Guarantor to incur any Indebtedness
(other than Acquired Indebtedness) or guarantee the payment of any Indebtedness
of the Company or any other Restricted Subsidiary unless (a) such Restricted
Subsidiary simultaneously executes and delivers a supplemental indenture to the
Indenture providing for a Guarantee of the Notes by such Restricted Subsidiary
which Guarantee will be subordinated to Guarantor Senior Indebtedness (but no
other Indebtedness) to the same extent that the Notes are subordinated to Senior
Indebtedness and (b), with respect to any guarantee of Subordinated Obligations
by a Restricted Subsidiary, any such guarantee shall be subordinated to such
Restricted Subsidiary's Guarantee at least to the same extent as such
Subordinated Obligations is subordinated to the Notes.

         (iii)   With respect to each supplemental indenture to the Indenture
delivered pursuant to the preceding paragraphs (i) and (ii), (a) each such
Restricted Subsidiary shall waive, and agree not in any manner whatsoever to
claim to take the benefit or advantage of, any rights of reimbursement,
indemnity or subrogation or any other rights against the Company or any other
Restricted Subsidiary as a result of any payment by such Restricted Subsidiary
under its Guarantee until such time as the obligations guaranteed thereby are
paid in full and (b) such Restricted Subsidiary shall deliver to the Trustee an
opinion of independent legal counsel to the effect that such Guarantee has been
duly executed and authorized and constitutes a valid, binding and enforceable
obligation of such Restricted Subsidiary, except insofar as 

                                       78
<PAGE>
 
enforcement thereof may be limited by bankruptcy, insolvency or similar laws
(including, without limitation, all laws relating to fraudulent transfer and
fraudulent conveyances) and except insofar as enforcement thereof is subject to
general principles of equity.

         (iv) Subject to the requirements described under "--Consolidation,
Merger, Sale of Assets, Etc.," any Guarantee by a Restricted Subsidiary of the
Notes shall provide by its terms that it shall be automatically and
unconditionally released and discharged (a) upon any sale, exchange or transfer,
to any person not an Affiliate of the Company, of all of the Company's Capital
Stock in, or all or substantially all the assets of, such Restricted Subsidiary,
which transaction is in compliance with the terms of the Indenture and such
Restricted Subsidiary is released from all guarantees and other security, if
any, by it of other Indebtedness of the Company or any Restricted Subsidiaries
or (b) at the request of the Company, if the holders of the Indebtedness of the
Company or any other Restricted Subsidiary, as the case may be, described in
clauses (i) and (ii) above unconditionally release their guarantee or Lien, as
the case may be, of such Restricted Subsidiary (including any deemed release
upon payment in full of all obligations under such Indebtedness), such release
and discharge to be effective at such time as, and for such periods that, (A) no
other Indebtedness of the Company or any other Restricted Subsidiary, as the
case may be, has been secured or guaranteed by such Restricted Subsidiary, as
the case may be, and (B) the holders of all such other Indebtedness which is
guaranteed by such Restricted Subsidiary also unconditionally release their
guarantee by, or Lien in assets or properties of, such Restricted Subsidiary
(including any deemed release upon payment in full of all obligations under such
Indebtedness).

     Reporting Requirements.  The Indenture requires that the Company file with
the Commission the annual reports, quarterly reports and other documents
required to be filed with the Commission pursuant to Sections 13 and 15(d) of
the Exchange Act, to the extent such filings are accepted by the Commission and
whether or not the Company has a class of securities registered under the
Exchange Act.  The Company is required to file with the Trustee, within 30 days
after it files them with the Commission, copies of such reports and documents
(with exhibits) and to cause such reports and documents (without exhibits) to be
distributed to all holders of the Notes then shown in the securities register.

CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.

     The Indenture provides that the Company will not, in any transaction or
series of related transactions, merge or consolidate with or into, or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets as an entirety to, any person or persons, and that
the Company will not permit any of the Restricted Subsidiaries to enter into any
such transaction or series of related transactions if such transaction or series
of related transactions, in the aggregate, would result in a sale, assignment,
conveyance, transfer, lease or other disposition of all or substantially all of
the properties and assets of the Company or of the Company and the Restricted
Subsidiaries, taken as a whole, to any other person or persons, unless at the
time and after giving effect thereto (i) either (A)(1) if the transaction or
transactions is a merger or consolidation involving the Company as a constituent
to the merger or consolidation, the Company shall be the surviving person of
such merger or consolidation or (2) if the transaction or related transactions
is a merger or consolidation involving a Restricted Subsidiary as a constituent
to the merger or consolidation, such Restricted Subsidiary shall be the
surviving person of such merger or consolidation and such surviving person shall
be a Restricted Subsidiary, or (B)(1) the person formed by such consolidation or
into which the Company or such Restricted Subsidiary is merged or to which the
properties and assets of the Company or such Restricted Subsidiary, as the case
may be, substantially as an entirety, are transferred (any such surviving person
or transferee person being the "Surviving Entity") shall be a corporation
organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia and (2) in the case of a transaction
involving the 

                                       79
<PAGE>
 
Company as a constituent to the merger or consolidation, or as the transferor of
all or substantially all of its assets or taken as a whole, all or substantially
all of the assets of it and the Restricted Subsidiaries, the Surviving Entity
shall expressly assume by a supplemental indenture executed and delivered to the
Trustee, in form satisfactory to the Trustee, all the obligations of the Company
under the Notes and the Indenture, and in each case, the Indenture shall remain
in full force and effect, (ii) immediately after giving effect to such
transaction or series of related transactions on a pro forma basis (including,
without limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or as a result of such transaction or series of related
transactions), no Default shall have occurred and be continuing and the Company,
or the Surviving Entity, as the case may be, after giving effect to such
transaction or series of related transactions on a pro forma basis, could incur
$1.00 of additional Indebtedness under the first paragraph of the "--Limitation
on Additional Indebtedness" covenant described above and (iii) each Guarantor
shall have executed and delivered to the Trustee, in form and substance
satisfactory to the Trustee, a supplemental indenture confirming such
Guarantor's Obligations to pay principal of and premium (if any) and interest on
the Notes pursuant to its Guarantee.

     In connection with any consolidation, merger, transfer, lease or other
disposition contemplated by the provisions described in the foregoing paragraph,
the Company shall deliver, or cause to be delivered, to the Trustee, in form
reasonably satisfactory to the Trustee, an officers' certificate and an opinion
of counsel, each stating that such consolidation, merger, transfer, lease or
other disposition and each supplemental indenture in respect thereof complies
with the requirements under the Indenture.

     The Indenture further provides that the Company will not permit any
Guarantor, in any transaction or series of related transactions, to merge or
consolidate with or into, or sell, assign, convey, transfer, lease or otherwise
dispose of all or substantially all of its properties and assets as an entirety
to any person or persons unless at the time and after giving effect thereto, (i)
either (a) the Guarantor will be the continuing corporation or (b) the person
(if other than the Guarantor and except in the case of a Guarantor that has been
disposed of in its entirety to another person, whether through merger,
consolidation or sale of Capital Stock or assets, if in connection therewith the
Company provides an officer's certificate to the Trustee to the effect that the
Company will comply with its obligations under "--Disposition of Proceeds of
Asset Sales" in respect of such disposition) formed by such consolidation or
into which such Guarantor is merged or the person which acquires by sale,
assignment, conveyance, transfer, lease or disposition all or substantially all
of the properties and assets of the Guarantor (the "Surviving Guarantor Entity")
will be a corporation duly organized and validly existing under the laws of the
United States of America, any State thereof or the District of Columbia and such
person expressly assumes, by a supplemental indenture, in a form satisfactory to
the Trustee, all the obligations of such Guarantor under its Guarantee and such
Guarantee will remain in full force and effect; (ii) immediately before and
immediately after giving effect to such transaction on a pro forma basis, no
Default or Event of Default will have occurred and be continuing; and (iii) at
the time of the transaction such Guarantor or the Surviving Guarantor Entity
will have delivered, or caused to be delivered, to the Trustee, in form and
substance reasonably satisfactory to the Trustee, an officers' certificate and
an opinion of counsel, each to the effect that such consolidation, merger,
transfer, sale, assignment, conveyance, transfer, lease or other transaction and
the supplemental indenture in respect thereof comply with the Indenture and that
all conditions precedent therein provided for relating to such transaction have
been complied with.

     Upon any consolidation or merger or any transfer of all or substantially
all of the assets of the Company, any Restricted Subsidiary which is not a
Guarantor, or any Guarantor in accordance with the foregoing, in which the
Company or such Guarantor, as the case may be, is not the Surviving Entity or
the Surviving Guarantor Entity, as the case may be, then such Surviving Entity
or Surviving Guarantor Entity, as the case may be, shall succeed to, and be
substituted for, and may exercise every right and power of, the 

                                       80
<PAGE>
 
Company or such Guarantor, as the case may be, under the Indenture or such
Guarantee, as the case may be, with the same effect as if the Surviving Entity
had been named as the Company therein or the Surviving Guarantor Entity had been
named the Guarantor therein, as the case may be, but neither the Company nor
such Guarantor, as the case may be, in the case of a lease by any of them of all
or substantially all of its assets shall be released from the obligation to pay
the principal of and premium (if any) and interest on the Notes or the
obligations of the Guarantee, as the case may be; provided that, solely for
purposes of computing cumulative Consolidated Net Income for purposes of clause
(B) of the first paragraph of the covenant "Limitation on Restricted Payments"
above, the cumulative Consolidated Net Income of any persons other than the
Company and the Restricted Subsidiaries shall only be included for periods
subsequent to the effective time of such merger, consolidation, combination or
transfer of assets.

     The Indenture provides that for all purposes of the Indenture and the Notes
(including the provision of this covenant and the covenants described in "--
Limitation on Additional Indebtedness", "--Limitation on Restricted Payments"
and "--Limitation on Liens"), Subsidiaries of any Surviving Entity will, upon
such transaction or series of transactions, become Restricted Subsidiaries or
Unrestricted Subsidiaries as provided pursuant to the covenant described under
"--Limitation on Designations of Unrestricted Subsidiaries" and all
Indebtedness, and all Liens on property or assets, of the Company and the
Restricted Subsidiaries immediately prior to such transaction or series of
transactions will be deemed to have been incurred upon such transaction or
series of transactions.

EVENTS OF DEFAULT

     The following are "Events of Default" under the Indenture:

          (i) default in the payment of the principal of, or premium, if any,

     redemption, upon required purchase, upon acceleration or otherwise); or

          (ii) default in the payment of an installment of interest on any of
     the Notes, when due and payable, and the continuation of such default for a
     period of 30 days or more; or

          (iii)  the failure by the Company, any Guarantor or any Restricted
     Subsidiary which is not a Guarantor to comply with its obligations
     described under "Consolidation, Merger, Sale of Assets, Etc." above, the
     failure to make or consummate a Change of Control Offer in accordance with
     the Company's obligations under the covenant described under "Change of
     Control" above, or the failure to make or consummate an offer in accordance
     with the Company's obligations under the covenant described under
     "Disposition of Proceeds of Asset Sales" above; or

          (iv) the failure by the Company, any Guarantor or any Restricted
     Subsidiary which is not a Guarantor to perform or observe any other term,
     covenant or agreement contained in the Notes, any Guarantee or the
     Indenture (other than a default specified in clause (i), (ii) or (iii)
     above) for a period of 30 days after written notice of such failure stating
     that it is a "notice of default" under the Indenture and requiring the
     Company to remedy the same shall have been given (x) to the Company by the
     Trustee or (y) to the Company and the Trustee by the holders of at least
     25% in aggregate principal amount of the Notes then outstanding; or

          (v) default or defaults under one or more agreements, instruments,
     mortgages, bonds, debentures or other evidences of Indebtedness (a "Debt
     Instrument") under which the Company, any Guarantor or any Restricted
     Subsidiary which is not a Guarantor or the Company and one or more

                                       81
<PAGE>
 
     Guarantors or Restricted Subsidiaries who are not Guarantors then have
     outstanding Indebtedness in excess of $10 million, individually or in the
     aggregate, and either (x) the principal amount of such Indebtedness is
     already due and payable in full or (y) such default or defaults have
     resulted in the acceleration of the maturity of such Indebtedness; or

          (vi) the commencement of proceedings, or the taking of any enforcement
     action (including by way of set-off), by any holder of at least $10 million
     in aggregate principal amount of Indebtedness of the Company, any Guarantor
     or any Restricted Subsidiary which is not a Guarantor, after a default
     under such Indebtedness, to retain in satisfaction of such Indebtedness or
     to collect or seize, dispose of or apply in satisfaction of such
     Indebtedness, property or assets of the Company, any Guarantor or any
     Restricted Subsidiary which is not a Guarantor having a Fair Market Value
     in excess of $10 million individually or in the aggregate; or

          (vii)  one or more judgments, orders or decrees of any court or
     regulatory or administrative agency of competent jurisdiction for the
     payment of money in excess of $10 million over the coverage under
     applicable binding insurance policies issued by a solvent insurer which has
     accepted such coverage, either individually or in the aggregate, shall be
     entered against the Company, any Guarantor or any Restricted Subsidiary
     which is not a Guarantor or any of their respective properties and shall
     not be discharged, settled or fully bonded and either (A) commencement by
     any creditor of an enforcement proceeding upon such judgment (other than a
     judgment that is stayed by reason of pending appeal or otherwise) or (B)
     there shall have been a period of 60 consecutive days after the date on
     which any period for appeal has expired and during which a stay of
     enforcement of such judgment, order or decree shall not be in effect; or

          (viii)  any Guarantee shall for any reason cease to be, or shall for
     any reason asserted by any Guarantor or the Company not be, in full force
     and effect and enforceable in accordance with its terms, except to the
     extent provided for by the Indenture and any such Guarantee; or

          (ix) certain events of bankruptcy, insolvency or bankruptcy
     reorganization with respect to the Company, any Guarantor or any
     Significant Subsidiary of the Company shall have occurred.

     If an Event of Default (other than as specified in clause (ix) above with
respect to the Company) shall occur and be continuing, the Trustee, by notice to
the Company, or the holders of at least 25% in aggregate principal amount of the
Notes then outstanding, by written notice to the Trustee and the Company, may
declare the principal of, premium, if any, and accrued interest on all of the
outstanding Notes due and payable immediately, upon which declaration all
amounts payable in respect of the Notes shall be immediately due and payable.
If an Event of Default specified in clause (ix) above with respect to the
Company occurs and is continuing, then the principal of, premium, if any, and
accrued interest on all of the outstanding Notes shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any holder of Notes.

     Notwithstanding the foregoing, if a declaration of acceleration in respect
of the Notes because an Event of Default specified in (i) clause (v) above shall
have occurred and be continuing, such Event of Default and any consequential
acceleration shall be automatically rescinded if the Indebtedness that is the
subject of such Event of Default has been repaid, or if the default relating to
such Indebtedness is waived or cured and, if such Indebtedness has been
accelerated, the holders thereof have rescinded their declaration of
acceleration in respect of such Indebtedness (provided, in each case, that such
repayment, waiver, cure or rescission is effected within a period of 10 days
from the continuation of such default beyond the applicable grace period or the
occurrence of such acceleration), or (ii) clause (vi) above shall have occurred

                                       82
<PAGE>
 
and be continuing, such Event of Default and any consequential acceleration
shall be automatically rescinded if the proceedings or enforcement action with
respect to the Indebtedness that is the subject of such Event of Default is
terminated or rescinded, or such Indebtedness is repaid and only so long as any
holder of such Indebtedness shall not have applied any property or assets
referenced in clause (vi) above in satisfaction of such Indebtedness, and, in
the case of both (i) and (ii) above, written notice of such repayment, or cure
or waiver and rescission, as the case may be, shall have been given to the
Trustee by the Company or by the requisite holders of such Indebtedness or a
trustee, fiduciary or agent for such holders, within 45 days after such
declaration of acceleration in respect of the Notes and no other Event of
Default shall have occurred which has not been cured or waived during such 45-
day period, and so long as such rescission of any such acceleration does not
conflict with any judgment or decree.

     After a declaration of acceleration under the Indenture, but before a
judgment or decree for payment of money due has been obtained by the Trustee,
the holders of a majority in aggregate principal amount of the outstanding
Notes, by written notice to the Company and the Trustee, may rescind such
declaration and its consequences if:  (a) the Company has paid or deposited with
the Trustee a sum sufficient to pay (i) all sums paid or advanced by the Trustee
under the Indenture and the reasonable compensation, expenses, disbursements,
and advances of the Trustee, its agents and counsel, (ii) all overdue interest
on all Notes, (iii) the principal of and premium, if any, on any Notes which
have become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Notes, and (iv) to the extent that payment of
such interest is lawful, interest upon overdue interest and overdue principal at
the rate borne by the Notes which has become due otherwise than by such
declaration of acceleration; (b) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction; and (c) all Events of
Default, other than the non-payment of principal of, premium, if any, and
interest on the Notes that has become due solely by such declaration of
acceleration, have been cured or waived.

     The holders of not less than a majority in aggregate principal amount of
the outstanding Notes may on behalf of the holders of all the Notes waive any
past default and its consequences under the Indenture except a default in the
payment of the principal of, premium, if any, or interest on any Note, or in
respect of a covenant or provision which under the Indenture cannot be modified
or amended without the consent of the holder of each Note outstanding.

     No holder of any of the Notes has any right to institute any proceeding
with respect to the Indenture or any remedy thereunder, unless such holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless the holders of at least 25% in aggregate principal amount of
the outstanding Notes have made written request, and offered reasonable security
or indemnity, to the Trustee to institute such proceeding within 30 days after
receipt of such notice and the Trustee, within such 30-day period, has not
complied with such request and has not received directions inconsistent with
such written request by holders of a majority in aggregate principal amount of
the outstanding Notes.  Such limitations do not apply, however, to a suit
instituted by a holder of a Note for the enforcement of the payment of the
principal of, premium, if any, or interest on, such Note on or after the
respective due dates expressed in such Note.

     During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent person would
exercise under the circumstances in the conduct of such person's own affairs.
Subject to the provisions of the Indenture relating to the duties of the
Trustee, whether or not an Event of Default shall occur and be continuing, the
Trustee is not under any obligation to exercise any of its rights or powers
under the Indenture at the request or direction of any of the holders of the
Notes unless such holders shall have offered to the Trustee reasonable security
or indemnity.  Subject to certain provisions 

                                       83
<PAGE>
 
concerning the rights of the Trustee, the holders of a majority in aggregate
principal amount of the outstanding Notes have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee under the
Indenture.

     If a Default or an Event of Default occurs and is continuing and is known
to the Trustee, the Trustee shall mail to each holder of the Notes notice of the
Default or Event of Default within 90 days after obtaining knowledge thereof.
Except in the case of a Default or an Event of Default in payment of principal
of, premium, if any, or interest on any Notes, the Trustee may withhold the
notice to the holders of such Notes if the Trustee in good faith determines that
withholding the notice is in the interest of the Noteholders.

     The Company is required to furnish to the Trustee annual and quarterly
statements as to the performance by the Company of its obligations under the
Indenture and as to any default in such performance.  The Company is also
required to notify the Trustee within ten business days of any event which is,
or after notice or lapse of time or both would become, an Event of Default;
provided, however, any Default based upon non-compliance with the foregoing
notification requirement may be (i) expressly waived or (ii) cured if the event
giving rise to the requirement for such notification shall have been waived or
cured, in each case, in accordance with the terms of the Indenture.

DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURE

     The Company may, at its option and at any time, terminate its obligations
with respect to the Notes then outstanding ("defeasance").  Such defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Notes then outstanding, except for (i) the
rights of holders of outstanding Notes to receive payment in respect of the
principal of, premium, if any, and interest on such Notes when such payments are
due, (ii) the Company's obligations to issue temporary Notes, register the
transfer or exchange of any Notes, replace mutilated, destroyed, lost or stolen
Notes and maintain an office or agency for receipt of payments in respect of the
Notes, (iii) the rights, powers, trusts, duties and immunities of the Trustee,
and (iv) the defeasance provisions of the Indenture.  In addition, the Company
may, at its option and at any time, elect to terminate its obligations with
respect to certain covenants that are set forth in the Indenture, some of which
are described under "--Certain Covenants" above, and any subsequent failure to
comply with such obligations shall not constitute a Default or an Event of
Default with respect to the Notes ("covenant defeasance").  If the Company
exercises its defeasance option or its covenant defeasance option, each
Guarantor will be released from all its obligations with respect to its
Guarantee.

     In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust for the benefit of
the holders of the Notes, cash in United States dollars, U.S. Government
Obligations (as defined in the Indenture), or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Notes to redemption or maturity, (ii) the Company
shall have delivered to the Trustee an opinion of counsel to the effect that the
holders of the outstanding Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance
or covenant defeasance had not occurred (in the case of defeasance, such opinion
must refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable federal income tax laws), (iii) no Default or Event of
Default (a) shall have occurred and be continuing on the date of such deposit or
(b) insofar as clause (ix) under the first paragraph under "--Events of Default"
is concerned, at any time during the period ending on the 91st day after the
date of deposit, (iv) such defeasance or covenant defeasance shall not cause the
Trustee 

                                       84
<PAGE>
 
to have a conflicting interest under the Indenture or the Trust Indenture Act
with respect to any securities of the Company, (v) such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a default
under, any other material agreement or instrument to which the Company is a
party or by which the Company is bound, and (vi) the Company shall have
delivered to the Trustee an officers' certificate and an opinion of counsel,
which, taken together, state that all conditions precedent under the Indenture
to either defeasance or covenant defeasance, as the case may be, have been
complied with and that no violations under agreements governing any other
outstanding Indebtedness would result therefrom.

SATISFACTION AND DISCHARGE

     The Indenture shall upon request of the Company cease to be of further
effect (except as to certain provisions governing registration of transfer and
exchange of the Notes and payments thereon) when (A) either (1) all Notes
theretofore authenticated and delivered (other than (i) Notes which have been
destroyed, lost or stolen and which have been replaced or paid and (ii) Notes
for whose payment (x) cash in United States dollars or (y) U.S. Government
Obligations maturing as to principal, premium, if any, and interest in such
amounts of money and at such times as are sufficient without consideration of
any reinvestment of such interest, to pay principal of and interest on the
outstanding Notes not later than one day before the due date of any payment,
have theretofore been deposited in trust with the Trustee or any Paying Agent)
have been delivered to the Trustee for cancellation, or (2) all such Notes not
theretofore delivered to the Trustee for cancellation (i) have become due and
payable, or (ii) will become due and payable at their Stated Maturity within one
year, or (iii) are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company, and the Company
or any Guarantor, in the case of (2)(i), (2)(ii) or (2)(iii) above, has
irrevocably deposited or caused to be deposited with the Trustee funds in an
amount sufficient to pay and discharge the entire indebtedness on such Notes not
theretofore delivered to the Trustee for cancellation, for principal and
interest to the date of such deposit (in the case of Notes which have become due
and payable) or to the Stated Maturity or Redemption Date, as the case may be,
together with instructions from the Company irrevocably directing the Trustee to
apply such funds to the payment thereof at maturity or redemption, as the case
may be; (B) the Company or any Guarantor has paid or caused to be paid all other
sums then due and payable hereunder by the Company; and (C) the Company has
delivered to the Trustee an officers' certificate and an opinion of counsel
which, taken together, state that all conditions precedent herein relating to
the satisfaction and discharge of this Indenture have been complied with.

AMENDMENTS AND WAIVERS

     From time to time, the Company, when authorized by a Board Resolution, the
Guarantors and the Trustee may, without the consent of the holders of any
outstanding Notes, amend, waive or supplement the Indenture or the Notes for
certain specified purposes, including, among other things, curing ambiguities,
defects or inconsistencies, qualifying, or maintaining the qualification of, the
Indenture under the Trust Indenture Act or making any change that does not
materially and adversely affect the rights of any holder. Other amendments or
modifications of the Indenture or the Notes may be made by the Company and the
Trustee with the consent of the holders of not less than a majority of the
aggregate principal amount of the outstanding Notes; provided that no such
modification or amendment may, without the consent of the holder of each
outstanding Note affected thereby, (i) reduce the principal amount of, extend
the fixed maturity of or alter the redemption provisions of the Notes, (ii)
change the currency in which the Notes or any premium or the interest thereon is
payable, (iii) reduce the percentage in principal amount of outstanding Notes
that must consent to an amendment, supplement or waiver or consent to take any
action under the Indenture or the Notes, (iv) impair the right to institute suit
for the enforcement of any payment on or with respect to the Notes, (v) waive a
default in payment with respect to the Notes, (vi) following the occurrence of a
Change 

                                       85
<PAGE>
 
of Control or Asset Sale, amend, change or modify the obligation of the Company
to make and consummate a Change of Control Offer in the event of a Change of
Control or make and consummate the offer with respect to any Asset Sale or
modify any of the provisions or definitions with respect thereto in a manner
adverse to the holders of the Notes, (vii) reduce or change the rate or time for
payment of interest on the Notes, (viii) modify or change any provision of the
Indenture affecting the subordination of the Notes or any Guarantee in a manner
adverse to the holders of the Notes or any such Guarantee or (ix) make any other
change in any Guarantee that could adversely affect a holder of a Note.

     Subject to the limitations set forth above, the holders of a majority in
aggregate principal amount of the outstanding Notes may waive compliance by the
Company with certain restrictive provisions of the Indenture.  The holders of a
majority in aggregate principal amount of the outstanding Notes may waive any
past default under the Indenture, except a default in the payment of principal
or premium, if any, or interest on the Notes.

THE TRUSTEE

     State Street Bank & Trust Company is the Trustee under the Indenture and
has been appointed by the Company as Registrar and Paying Agent with regard to
the Notes.

     The Indenture (including the provisions of the Trust Indenture Act
incorporated by reference therein) contains limitations on the rights of the
Trustee thereunder, should it become a creditor of the Company, to obtain
payment of claims in certain cases or to realize on certain property received by
it in respect of any such claims, as security or otherwise.  The Trustee is
permitted to engage in other transactions; provided, however, if it acquires any
conflicting interest (as defined in the Trust Indenture Act) it must eliminate
such conflict or resign.

GOVERNING LAW

     The Indenture, the Notes and the Guarantees are governed by the laws of the
State of New York, without regard to the principles of conflicts of law.

CONSENT TO JURISDICTION AND SERVICE

     The Indenture provides that each of the Company and the Guarantors
irrevocably appoint Corporation Trust System as its agent for service of process
in any suit, action or proceeding with respect to the Indenture, any Guarantee
or the Notes and for actions brought under federal or state securities laws
brought in any federal or state court located in The City of New York and
submits to such jurisdiction.

<PAGE>
 
securities, by contract or otherwise; and the terms "controlling" and
"controlled" have meanings correlative to the foregoing. For purposes of this
definition, beneficial ownership of 10% or less of the voting common equity (on
a fully diluted basis) or options or warrants to purchase such equity (but only

this "Consolidated Fixed Charge Coverage Ratio", (i) interest on outstanding
Indebtedness determined on a fluctuating basis as of the Transaction Date and

<PAGE>
 
might constitute Indebtedness, amounts owing for goods, materials or services

other current liabilities (other than any current liabilities owing under the
Credit Facility Obligations or the current portion of any long-term Indebtedness
which would constitute Senior Indebtedness but for the operation of this clause

holder or holders of such Indebtedness or their representative or the Company
shall have furnished to the Trustee an opinion, unqualified in all material
respects, of independent legal counsel, addressed to the Trustee (which legal
counsel may, as to matters of fact, rely upon a certificate of the Company) to

affect the priorities of any Indebtedness arising solely by operation of law in
any case or proceeding or similar event described in clause (a), (b) or (c) of
the second paragraph of "--Subordination."

     "Senior Subordinated Obligations" means, with respect to the Company or any

of payment and is not subordinated by its terms in right of payment to any
Indebtedness or other obligation of the Company or such Guarantor, which is not
Senior Indebtedness of the Company or such Guarantor.

least a majority ownership interest entitled to vote in the election of
directors, members, partners, managers, officers, agents or trustees thereof (or
other person performing similar functions) or is a general partner (or serves in

BOOK ENTRY DELIVERY AND FORM

     The 144A Notes offered and sold to Qualified Institutional Buyers in
reliance on Rule 144A under the Securities Act are represented by two permanent
Global Notes in definitive, fully registered book-entry form (the "Rule 144A
Global Notes") and are registered in the name of Cede & Co., as nominee of the
DTC, on behalf of purchasers of the 144A Notes represented thereby for credit to
the respective accounts of such purchasers (or to such other accounts as they
may direct) at the DTC.

     The certificates representing the Exchange Notes will be issued in fully
registered form.  Except as described in the next paragraph, the Exchange Notes
initially will be represented by a single, permanent Global Exchange Note, in
definitive, fully registered form without interest coupons (the "Global Exchange
Note" and together with the Rule 144A Global Notes, the "Global Notes"), and the
Global Exchange Note 

                                       99
<PAGE>
 
will be deposited with the Trustee as custodian for the DTC and registered in
the name of Cede & Co. or such other nominee as the DTC may designate.

     Holders of Notes who elect to take physical delivery of their certificates
instead of holding their interest through a Global Note (collectively referred
to herein as the "Non-Global Holders") will be issued in registered form a
certificated Note ("Certificated Note").  Upon the transfer of any Certificated
Note initially issued to a Non-Global Holder, such Certificated Note will,
unless the transferee requests otherwise or the Global Note has previously been
exchanged in whole for Certificated Notes, be exchanged for an interest in the
appropriate Global Note.

THE GLOBAL NOTES

     The Company expects that pursuant to procedures established the by the DTC
(a) upon deposit of the Global Exchange Note, the DTC or its custodian will
credit on its internal system portions of the Global Exchange Note, as
appropriate, to the respective accounts of persons who own beneficial interests
in the Global Exchange Note and who have accounts with such depositary and (b)
ownership of the Exchange Notes will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by the DTC or its
nominee (with respect to interests of Participants (as defined below) and the
records of Participants (with respect to interests of persons other than
Participants)). Ownership of beneficial interests in the Global Exchange Note
will be limited to persons who have accounts with the DTC ("Participants") or
persons who hold interests through Participants. Holders may hold their
interests in the Global Exchange Note directly through the DTC if they are
Participants in such system or, if they are not Participants, indirectly through
organizations which are Participants in such system.

     So long as the DTC or its nominee is the registered owner of a Global Note,
the DTC or such nominee, as the case may be, will be considered the sole owner
or holder of the Notes represented by the Global Note for all purposes under the
Indenture and the Notes. Except as provided below, owners of beneficial
interests in a Global Note will not be entitled to have Notes represented by
such Global Note registered in their names, will not receive or be entitled to
receive physical delivery of Certificated Notes, and will not be considered the
owners or holders thereof under the Indenture for any purpose, including with
respect to the giving of any directions, instruction or approval to the Trustee
thereunder. As a result, the ability of a person having a beneficial interest in
Notes represented by a Global Note to pledge or transfer such interest to
persons or entities that do not participate in the DTC system or to otherwise
take action with respect to such interest may be affected by the lack of a
physical certificate evidencing such interest. No beneficial owner of an
interest in the Global Exchange Note will be able to transfer such interest
except in accordance with the applicable procedures of the DTC, in addition to
those provided for under the Indenture.

     Each person owning a beneficial interest in a Global Note must rely on the
procedures of the DTC and, if such person is not a Participant or an Indirect
Participant (as defined below), on the procedures of the Participant through
which such person owns its interest, to exercise any rights of a Holder of Notes
under the Indenture or such Global Note. The Company understands that under
existing industry practice, if the Company requests any action of Holders of
Notes, or a person that is an owner of a beneficial interest in a Global Note
desires to take any action that the DTC, as the Holder of such Global Note, is
entitled to take, the DTC would authorize the Participants to take such action
and the Participants would authorize persons owning through such Participants to
take such action or would otherwise act upon the instruction of such persons.
Neither the Company nor the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of Notes
by the DTC, or for maintaining, supervising or reviewing any records of the DTC
relating to such Notes or for any other matter relating to the actions or
procedures of the DTC.

                                      100
<PAGE>
 
     Payments with respect to the principal of, premium, if any, and interest
on, any Notes represented by a Global Note registered in the name of DTC or its
nominee on the applicable record date will be payable by the Trustee to or at
the direction of the DTC or its nominee in its capacity as the registered Holder
of the Global Note representing such Notes under the Indenture. Under the terms
of the Indenture, the Company and the Trustee may treat the persons in whose
names the Notes, including the Global Notes, are registered as the owners
thereof for the purpose of receiving such payment and for any and all other
purposes whatsoever. Consequently, neither the Company nor the Trustee has or
will have any responsibility or liability for the payment of such amounts to
beneficial owners of interests in the Global Note (including principal, premium,
if any, and interest). The Company believes, however, that it is currently the
policy of the DTC to immediately credit the accounts of the relevant
Participants with such payment, in amounts proportionate to their respective
holdings in principal amount of beneficial interests in the relevant Notes as
shown on the records of the DTC. Payments by Participants and Indirect
Participants to the beneficial owners of Notes will be governed by standing
instructions and customary practice and will be the responsibility of the
Participants or the Indirect Participants and the DTC.

     Transfers between Participants in the DTC will be effected in accordance
with the DTC's rules and will be settled in immediately available funds. If a
Holder requires physical delivery of a Certificated Note for any reason,
including to sell Notes to persons in states which require physical delivery of
such Notes or to pledge such Notes, such Holder must transfer its interest in
the Global Note in accordance with the procedures of the DTC and in accordance
with the procedures set forth in the Indenture.

     The DTC has advised the Company as follows: the DTC is a limited purpose
trust company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. The DTC was created to hold
securities for its Participants and facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
changes in accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers (including the Initial Purchasers), banks, trust companies, clearing
corporations and certain other organizations. Indirect access to the DTC system
is available to others such as banks, brokers, dealers and trust companies
(collectively, the "Indirect Participants") that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly.
Persons who are not Participants may beneficially own securities held by or on
behalf of the DTC only through the DTC's Participants or Indirect Participants.

     Although the DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Notes among Participants of the
DTC, it is under no obligation to perform such procedures, and such procedures
may be discontinued at any time. None of the Company, the Trustee, the Registrar
or the Paying Agent will have any responsibility for the performance by the DTC,
Participants or Indirect Participants of their obligations under the rules and
procedures governing their operations.

     The information in this section concerning the DTC and the DTC's book-entry
system has been obtained from sources the Company believes to be reliable, but
the Company takes no responsibility for the accuracy thereof.

CERTIFICATED NOTES

     Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the Trustee, exchange such beneficial interest
for Notes in the form of Certificated Notes. Upon any such issuance, the Trustee
is required to register such Notes in the name of, and cause the

                                      101
<PAGE>
 
same to be delivered to, such person or persons (or the nominee of any thereof).
In addition, if (a) the DTC or any successor depositary (the "Depositary")
notifies the Company in writing that the Depositary is no longer willing or able
to act as a depositary and the Company is unable to locate a qualified successor
within 90 days or (b) an Event of Default has occurred and is continuing with
respect to the Notes, then, upon surrender by the registered owner or Holder of
a Global Note (a "Global Note Holder") of its Global Note, Notes in the form of
Certificated Notes will be issued to each person that such Global Note Holder
and the Depositary identify as the beneficial owner of the related Notes.

     Neither the Company nor the Trustee will be liable for any delay by the
related Global Note Holder or the Depositary in identifying the beneficial
owners of the related Notes, and each such person may conclusively rely on, and
will be protected in relying on, instructions from such Global Note Holder or
the Depositary for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Notes to be issued).

                   DESCRIPTION OF CERTAIN FEDERAL INCOME TAX
              CONSEQUENCES OF AN INVESTMENT IN THE EXCHANGE NOTES

     The following is a summary of the material United States federal income tax
consequences of the acquisition, ownership and disposition of the Exchange Notes
by a United States Holder (as defined below). This summary deals only with
United States Holders that will hold the Exchange Notes as capital assets. The
discussion does not cover all aspects of federal taxation that may be relevant
to, or the actual tax effect that any of the matters described herein will have
on, the acquisition, ownership or disposition of the Exchange Notes by
particular investors, and does not address state, local, foreign or other tax
laws.  In particular, this summary does not discuss all of the tax
considerations that may be relevant to certain types of investors subject to
special treatment under the federal income tax laws (such as banks, insurance
companies, investors liable for the alternative minimum tax, individual
retirement accounts and other tax-deferred accounts, tax-exempt organizations,
dealers in securities or currencies, investors that will hold the Exchange Notes
as part of straddles, hedging transactions or conversion transactions for
federal tax purposes or investors whose functional currency is not United States
dollars). Furthermore, the discussion below is based on provisions of the Code,
and regulations, rulings and judicial decisions thereunder as of the date
hereof, and such authorities may be repealed, revoked or modified so as to
result in United States federal income tax consequences different from those
discussed below. EACH HOLDER OF 144A NOTES SHOULD CONSULT ITS OWN TAX ADVISORS
CONCERNING THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES IN LIGHT OF ITS
PARTICULAR SITUATION, AS WELL AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY
STATE, LOCAL OR FOREIGN TAXING JURISDICTION.

     As used herein, the term "United States Holder" means a beneficial owner of
the Exchange Notes that is (i) a citizen or resident of the United States for
United States federal income tax purposes, (ii) a corporation created or
organized under the laws of the United States or any State thereof, (iii) a
person or entity that is otherwise subject to United States federal income tax
on a net income basis in respect of income derived from the Exchange Notes, or
(iv) a partnership to the extent the interest therein is owned by a person who
is described in clause (i), (ii) or (iii) of this paragraph.

INTEREST

     Interest paid on an Exchange Note will be taxable to a United States Holder
as ordinary income at the time it is received or accrued, depending on the
holder's method of accounting for tax purposes.

                                      102
<PAGE>
 
ORIGINAL ISSUE DISCOUNT

     Under the applicable provisions of the Code, the 144A Notes were issued
with no original issue discount for federal income tax purposes. Because the
Exchange Notes should be treated as a continuation of the 144A Notes, there also
should be no original issue discount applicable to the Exchange Notes.

PURCHASE, SALE, EXCHANGE, RETIREMENT AND REDEMPTION OF THE EXCHANGE NOTES

     In general (with certain exceptions described below), a United States
Holder's tax basis in an Exchange Note should equal the price paid for the 144A
Notes for which such Exchange Note was exchanged pursuant to the Exchange Offer.
A United States Holder generally will recognize gain or loss on the sale,
exchange, retirement, redemption or other disposition of an Exchange Note (or
portion thereof) equal to the difference between the amount realized on such
disposition and the United States Holder's tax basis in the Exchange Note (or
portion thereof).  Except to the extent attributable to accrued but unpaid
interest, gain or loss recognized on such disposition of an Exchange Note will
be capital gain or loss and will be long-term capital gain or loss if such
Exchange Note is held for more than one year and will be subject to tax at a
reduced rate if such Exchange Note is held for more than 18 months.

BOND PREMIUM

     If a United States Holder acquired a 144A Note for an amount more than the
amount payable at maturity (or at an earlier call date if a smaller premium
would result), the Holder may elect to amortize and deduct such bond premium on
a yield to maturity basis. Once made, such an election applies to all bonds
(other than bonds the interest on which is excludable from gross income) held by
the United States Holder at the beginning of the first taxable year to which the
election applies or thereafter acquired by the United States Holder, unless the
IRS consents to a revocation of the election. The basis of an Exchange Note will
be reduced by any amortizable bond premium taken as a deduction.

MARKET DISCOUNT

     The receipt of an Exchange Note in exchange for a 144A Note purchased other
than at original issue may be affected by the market discount provisions of the
Code. These rules generally provide that, subject to a statutorily defined de
minimis exception, if a United States Holder purchased a 144A Note at a "market
discount," as defined below, and thereafter recognizes gain upon a disposition
of the Exchange Note acquired in exchange therefor (including dispositions by
gift or redemption), the lesser of such gain (or appreciation, in the case of a
gift) or the portion of the market discount that has accrued ("accrued market
discount") while the Exchange Note (and its predecessor 144A Note, if any) was
held by such United States Holder will be treated as ordinary interest income at
the time of disposition rather than as capital gain. For a 144A Note, "market
discount" is the excess of the stated redemption price at maturity over the tax
basis immediately after its acquisition by a United States Holder. Market
discount generally will accrue ratably during the period from the date of
acquisition to the maturity date of the Note, unless the United States Holder
elects to accrue such discount on the basis of the constant yield method. Such
an election applies only to the Note with respect to which it is made and is
irrevocable.

     In lieu of including the accrued market discount in income at the time of
disposition, a United States Holder of an Exchange Note acquired in exchange for
a 144A Note

                                      103
<PAGE>
 
acquired at a market discount may elect to include the accrued market discount
in income currently either ratably or using the constant yield method. Once
made, such an election applies to all other obligations that the United States
Holder purchases at a market discount during the taxable year for which the
election is made and in all subsequent taxable years of the United States
Holder, unless the IRS consents to a revocation of the election. If an election
is made to include accrued market discount in income currently, the basis of the
Note in the hands of the United States Holder will be increased by the accrued
market discount thereon as it is includable in income. A United States Holder of
a market discount Note who does not elect to include market discount in income
currently generally will be required to defer deductions for interest on
borrowings allocable to such Note, if any, in an amount not exceeding the
accrued market discount on such Note until the maturity or disposition of such
Note.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     Payments of interest on, and the proceeds of sale or other disposition of
the Notes payable to a United States Holder may be subject to information
reporting requirements, and backup withholding at a rate of 31% will apply to
such payments if, among other things, the United States Holder fails to provide
an accurate taxpayer identification number or to report all interest and
dividends required to be shown on its federal income tax returns. Certain United
States Holders (including, among others, corporations) are not subject to backup
withholding on such payments. United States Holders should consult their tax
advisors as to their qualification for exemption from backup withholding and the
procedure for obtaining such an exemption.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer in exchange for 144A Notes that were acquired by
such broker-dealer as a result of market-making activities or other trading
activities (a "Participating Broker-Dealer") must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer in connection with resales of any such Exchange
Notes. Newpark has agreed that, starting on the Expiration Date and ending on
the close of business on the 180/th/ day following the Expiration Date, it will
make this Prospectus, as amended or supplemented, available to any Participating
Broker-Dealer for use in connection with any such resale.

     Newpark will not receive any proceeds from any sales of Exchange Notes by
Participating Broker-Dealers. Exchange Notes received by Participating Broker-
Dealers may be sold from time to time, in one or more transactions on one or
more exchanges (Newpark intends to apply for listing of the Exchange Notes on
the NYSE, but there can be no assurance that such application will be approved),
in the over-the-counter market, in negotiated transactions, through the writing
of options on the Exchange Notes or a combination of such methods of resale, at
market prices prevailing at the time of resale, at prices related to such
prevailing market prices or at negotiated prices. Any such resales may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any Participating
Broker-Dealer that resells such Exchange Notes. Any Participating Broker-Dealer
and any broker-dealer that participates in a distribution of Exchange Notes may
be deemed to be an "underwriter" within the meaning of the Securities Act and
any profit on any such resale of Exchange Notes and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a
Participating

                                      104
<PAGE>
 
Broker-Dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.  See "The Exchange Offer--Resale of the Exchange 
Notes."

     For a period of 180 days after the Expiration Date, Newpark will promptly
send additional copies of this Prospectus and any amendment or supplement of
this Prospectus to any Participating Broker-Dealer that requests such documents
in the Letter of Transmittal.  Newpark and the Guarantors have agreed to pay
certain expenses incident to the Exchange Offer and will indemnify the holders
of the 144A Notes against certain liabilities, including certain liabilities
that may arise under the Securities Act.

                                 LEGAL MATTERS

     Certain legal matters will be passed upon for the Issuers by Ervin, Cohen &
Jessup LLP, Beverly Hills, California.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders of
Newpark Resources, Inc.
 
  We have audited the accompanying consolidated balance sheets of Newpark
Resources, Inc. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of income, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Newpark Resources, Inc. and
subsidiaries at December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1996 in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(INFORMATION WITH RESPECT TO SEPTEMBER 30, 1996 AND 1997 AND THE NINE MONTH
PERIODS THEN ENDED IS UNAUDITED)
 
A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  ORGANIZATION AND PRINCIPLES OF CONSOLIDATION. Newpark Resources, Inc.
("Newpark" or the "Company") provides comprehensive environmental management
and oilfield construction services to the oil and gas industry in the Gulf
Coast region, principally Louisiana and Texas. The consolidated financial
statements include the accounts of the Company and its wholly-owned
subsidiaries. All financial statements have been restated to include the
effects of the Sampey, Bilbo, Meschi, Drilling Fluids Management, Inc. ("SBM")
acquisition that was accounted for as a pooling of interests. All material
intercompany transactions are eliminated in consolidation.
 
  USE OF ESTIMATES. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  CASH EQUIVALENTS. All highly liquid investments with a remaining maturity of
three months or less at the date of acquisition are classified as cash
equivalents.
 
  FAIR VALUE DISCLOSURES. Statement of Financial Accounting Standards ("SFAS")
No. 107, "Disclosures about Fair Value of Financial Instruments", requires the
disclosure of the fair value of all significant financial instruments. The
estimated fair value amounts have been developed based on available market
information and appropriate valuation methodologies. However, considerable
judgment is required in developing the estimates of fair value. Therefore,
such estimates are not necessarily indicative of the amounts that could be
realized in a current market exchange. After such analysis, management
believes the carrying values of the Company's significant financial
instruments (consisting of cash and cash equivalents, receivables, payables
and long-term debt) approximate fair values at December 31, 1996 and 1995.
 
  INVENTORIES. Inventories are stated at the lower of cost (principally
average and first-in, first-out) or market. Such inventories consist of logs,
supplies, and board road lumber. Board road lumber is amortized on the
straight-line method over its estimated useful life of approximately one year.
 
  DEPRECIATION AND AMORTIZATION. Depreciation of property, plant and
equipment, including interlocking board road mats, is provided for financial
reporting purposes on the straight-line method over the estimated useful lives
of the individual assets which range from three to forty years. For income tax
purposes, accelerated methods of depreciation are used.
 
  The cost in excess of net assets of purchased businesses ("excess cost") is
being amortized on a straight-line basis over twenty-five to forty years,
except for $2,211,000 relating to acquisitions prior to 1971 that is not being
amortized. Management of the Company periodically reviews the carrying value
of the excess cost in relation to the current and expected operating results
of the businesses which benefit therefrom in order to assess whether there has
been a permanent impairment of the excess cost of the net purchased assets.
Accumulated amortization on excess cost was $1,253,000 and $437,000 at
December 31, 1996 and 1995, respectively.
 
  REVENUE RECOGNITION. Revenues from certain contracts, which are typically of
short duration, are reported as income on a percentage-of-completion method.
Contract revenues are recognized in the proportion that costs incurred bear to
the estimated total costs of the contract. When an ultimate loss is
anticipated on a contract, the entire estimated loss is recorded. Included in
accounts receivable are unbilled revenues in the amounts of $6,600,000 and
$8,600,000 at December 31, 1996 and 1995, respectively, all of which are due
within a one year period.

                            NEWPARK RESOURCES, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  INCOME TAXES. Income taxes are provided using the liability method in
accordance with SFAS No. 109, "Accounting for Income Taxes." Under this
method, deferred income taxes are recorded based upon differences between the
financial reporting and income tax basis of assets and liabilities and are
measured using the enacted income tax rates and laws that will be in effect
when the differences are expected to reverse.
 
  NON-RECURRING EXPENSE. Results for the 1995 period include $436,000 of non-
recurring cost associated with a proposed merger which was not completed.
 
  INTEREST CAPITALIZATION. For the years ended December 31, 1996, 1995 and
1994 the Company incurred interest cost of $4,415,000, $4,291,000, and
$2,869,000 of which $515,000, $458,000, and $145,000, respectively, was
capitalized on qualifying construction projects. For the nine months ended
September 30, 1997 and 1996 the Company incurred interest cost of $3,461,000
and $3,296,000, respectively, of which $758,000 and $442,000, respectively,
was capitalized on qualified construction projects.
 
  INCOME PER SHARE. Primary and fully diluted net income per share is based on
the weighted average number of shares of common stock and common stock
equivalents outstanding during the year. Common stock equivalents consist of
stock options. All per share and weighted average share amounts have been
restated to give retroactive effect to a 2-for-1 stock split, effected in the
form of a 100% stock dividend, approved by the Board of Directors on October
27, 1997, a 2-for-1 stock split approved by the stockholders on May 14, 1997
and a 5% stock dividend declared and paid during 1995.
 
  STOCK-BASED COMPENSATION. SFAS No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123") encourages, but does not require, companies to
record compensation cost for stock-based employee compensation plans at fair
value. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees,"
and related interpretations and has adopted the disclosure-only provisions of
SFAS 123. Accordingly, compensation cost for stock options is measured as the
excess, if any, of the quoted market price of the Company's stock at the date
of the grant over the amount an employee must pay to acquire the stock. See
Note H.
 
  NEW ACCOUNTING PRONOUNCEMENTS. In February 1997, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards Number 128
"Earnings per share" ("SFAS 128") which changes the method of calculating
earnings per share (EPS). SFAS 128 requires the presentation of "basic" EPS
and "diluted" EPS on the face of the statement of income. Basic EPS is
computed by dividing the net income available to common stockholders by the
weighted average shares of outstanding common stock. The calculation of
diluted EPS is similar to basic EPS except that the denominator includes
dilutive common stock equivalents such as stock options and warrants. The
statement is effective for financial statements for periods ending after
December 31, 1997. The Company will adopt SFAS 128 in the fourth quarter of
1997, as early adoption is not permitted. The adoption of this standard will
not have a significant impact on the Company's reported EPS amounts.
 
  RECLASSIFICATIONS. Certain reclassifications of prior year amounts have been
made to conform to the current year presentation.
 
B. ACQUISITIONS AND DISPOSITIONS
 
  On August 12, 1996, the Company acquired from Campbell Wells, Ltd.
("Campbell") substantially all of the non-landfarm assets and certain leases
associated with five transfer stations located along the Gulf Coast and three
receiving docks at the landfarm facilities operated by Campbell for cash
consideration of $70.5 million.

                            NEWPARK RESOURCES, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

This acquisition has been accounted for under the purchase method and the
results of the operations of the acquired business have been included in the
consolidated financial statements since the date of acquisition. The purchase
price was allocated based on estimated fair values at the date of acquisition.
This resulted in an excess of purchase price over assets acquired of $77.2
million, of which $68.7 million is being amortized on a straight-line basis
over 35 years, and $8.5 million is being amortized on a straight-line basis
over 25 years.
 
  The following unaudited pro forma information presents a summary of
consolidated results of operations of the Company and Campbell as if the
acquisition and the related equity offering had occurred January 1, 1995.

  These unaudited pro forma results have been prepared for comparative
purposes only and include certain adjustments, such as additional amortization
expense as a result of goodwill, the net effect on operating costs related to
the combined operations, reduced interest expense as a result of debt
reduction from the proceeds of the offering, and the net impact of the above
adjustments on income tax expense. They do not purport to be indicative of the
results of operations which actually would have resulted had the combination
been in effect on January 1, 1995, or of future results of operations of the
consolidated entities.
 
  Concurrent with the Campbell acquisition, the Company entered into an
agreement to provide a certain volume of waste over a future period to
Campbell. See further discussion in Note J.
 
  In conjunction with this acquisition and the acquisition of a new waste
disposal license, the Company recorded a third quarter restructure charge of
$2.4 million, $1.6 million after taxes, or $0.03 per common share. A total of
approximately $1.8 million was related to the restructuring of certain of the
Company's NOW processing operations and staffing changes to facilitate the
integration of its operations with those recently acquired by Campbell. The
Company recognized an additional $.6 million of non-recurring costs associated
with the termination of processing operations at its original NORM facility at
Port Arthur, Texas and the partial closure of the site.
 
  On August 29, 1996, the Company sold the land, buildings and certain
equipment comprising substantially all of the assets of its former marine
repair operation to the operator of the facility and refinanced certain
advances previously made to the operator. The assets sold had previously been
subject to an operating lease to the same party, and the purchase was made
under the terms of a purchase option granted in the original lease. The sales
price of approximately $16.0 million represents the net book value of the
assets sold and refinanced. The consideration received included $1.2 million
in cash, $7.2 million in notes receivable, and $7.6 million in debt
obligations, which were assumed by the operator. The notes receivable are
included in other assets and have been recorded at their estimated fair value
which approximates the amount at which they can be prepaid at the operator's
options during the term of the notes. The notes receivable include two notes,
one of which is in the face amount of $8,534,000, bears interest at 5.0% per
annum, with interest and principal payable at September 30, 2003. The second
note is in the face amount of $600,000, bears interest at 8.0% per annum and
is payable in monthly and annual installments of principal and interest
through September 30, 2003. Both notes are secured by a second lien on the
assets sold as well as certain guarantees of the operator. The Company has
guaranteed certain of the debt obligations of the operator, which is limited
to a maximum of $10 million and reduces proportionately with debt repayments
made by the operator.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  On February 28, 1997, Newpark issued 2,328,000 shares of its common stock in
exchange for all of the outstanding common stock of SBM. SBM is a full service
drilling fluids company serving the onshore and offshore Louisiana and Texas
Gulf Coast drilling markets. This business combination has been accounted for
as a pooling of interests, and accordingly, the consolidated financial
statements for periods prior to the combination have been restated to include
the accounts and results of operations of SBM.
 
  Prior to the combination SBM's fiscal year end was October 31. Newpark's
fiscal year is December 31. In applying pooling of interests accounting, the
December 31, Newpark consolidated financial statements were combined with the
October 31 SBM financial statements for all years presented.
 
  Operating results prior to the combination of the separate companies and the
combined amounts presented in the consolidated financial statements are
summarized below:

  In addition to SBM, Newpark acquired several other companies in 1997.
Certain of these acquisitions have been accounted for by the purchase method
and include the results of operations of the acquired companies since their
respective acquisition dates in 1997. These acquisitions were completed in
exchange for an aggregate of 1,193,332 shares of Newpark common stock. The
historical results of operations related to these acquisitions individually
and in the aggregate were not considered significant in relation to the
financial reporting requirements of Newpark.
 
  Also during 1997, Newpark acquired two additional companies, the
acquisitions of which have been accounted for as pooling of interests. These
combinations were completed in exchange for an aggregate of 1,168,000 shares
of Newpark common stock. Prior year financial statements have not been
restated because the financial information related to these entities
individually and in the aggregate were not considered significant in relation
to the financial reporting requirements of Newpark. The results of operations
related to these entities during 1997, prior to the combination dates, were
also not considered significant.

  As of September 30, 1997, the Company maintained a $90.0 million bank credit
facility in the form of a revolving line of credit commitment. As of December
31, 1996, the Company maintained a $60.0 million bank credit facility with
$25.0 million in the form of a revolving line of credit commitment and $35.0
million in a term note. The credit facility is secured by a pledge of
substantially all of the Company's accounts receivable, inventory and
property, plant, and equipment. It bears interest at either a specified prime
rate (8.25% at December 31, 1996 and 8.5% at September 30, 1997) or the LIBOR
rate (5.563% at December 31, 1996 and 5.77% at September 30, 1997) plus a
spread which is determined quarterly based upon the ratio of the Company's
funded debt to cash flow. The average interest rate for the year ended
December 31, 1996 was 7.41%. The line of credit requires monthly interest
payments and matures on June 30, 2000. At December 31, 1996, $1.8 million of
letters of credit were issued and outstanding, leaving a net of $23.2 million
available for cash advances under the line of credit, against which $11.8
million had been borrowed. At September 30, 1997, $2.0 million of letters of
credit were issued and outstanding and $73.07 million had been borrowed. The
outstanding balance on the term note at December 31, 1996 was $27.2 million.
The average interest rate for the year ended December 31, 1996 was 7.82%. The
credit facility requires that the Company maintain certain specified financial
ratios and comply with other usual and customary requirements. The Company was
in compliance with the respective agreements at December 31, 1996 and at
September 30, 1997.
 
  In November 1996, an amendment to the credit facility was approved by the
banks, which eliminated the monthly borrowing base determination, reduced
certain of the restrictive and compliance covenants contained in the facility,
and reduced the frequency of financial reporting.

  The Company also had an additional revolving credit loan agreement whereby
it could borrow a maximum of $2,500,000. Borrowings under this revolving
credit loan agreement were limited to the amount of certain accounts
receivable and inventory. The aggregate advances outstanding as of December
31, 1996 totaled $2,350,000, due August 30, 1997. Under the terms of the
agreement, interest was payable monthly at the bank's prime rate plus 1%. This
line of credit was paid in full subsequent to December 31, 1996.
 
  Maturities of long-term debt are $11,736,000 in 1997, $21,099,000 in 1998,
$8,466,000 in 1999, $4,105,000 in 2000, $180,000 in 2001 and $1,068,000
thereafter.

  For federal income tax purposes, the Company has net operating loss
carryforwards ("NOLs") of approximately $10 million (net of amounts disallowed
pursuant to IRC Section 382) that, if not used, will expire in 1999 through
2010. The Company also has approximately $4 million of alternative minimum tax
credit carryforwards, which are not subject to expiration and are available to
offset future regular income taxes subject to certain limitations. These
carryforwards have been recognized for financial reporting purposes.

  Under SFAS No. 109 a valuation allowance must be established to offset a
deferred tax asset if, based on the weight of available evidence, it is more
likely than not that some portion or all of the deferred tax asset will not be
realized. At December 31, 1995, the deferred tax liabilities of the
consolidated group exceeded the deferred tax assets, therefore a deferred tax
benefit was recorded for the full amount of the remaining federal NOLs. The
valuation allowance at December 31, 1995, related to certain state NOLs that
were not yet recognized in the financial statements. At December 31, 1996, the
Company recognized a deferred tax benefit for these state NOLs for financial
reporting purposes. The Company believes that its estimate of future earnings
based on contracts in place, the overall improved gas market, and its prior
earnings trend supports the recorded net state deferred tax asset.
 
F. PREFERRED STOCK
 
  The Company has been authorized to issue up to 1,000,000 shares of Preferred
Stock, $.01 par value, none of which are issued or outstanding at September
30, 1997.
 
G. COMMON STOCK
 
  On May 14, 1997, the stockholders of the Company approved an increase in the
number of authorized common stock shares to 80,000,000. This allowed the
Company to effect a 2-for-1 stock split authorized by the Board of Directors
on February 26, 1997. Another 2-for-1 stock split, effected in the form of a
100% stock dividend, was approved by the Board of Directors on October 27,
1997. All share and per share amounts have been adjusted retroactively to
reflect these stock splits.

H. STOCK OPTION PLANS
 
  At December 31, 1996, the Company had four stock-based compensation plans,
which are described below. The Company applies Accounting Principles Board
Opinion 25 ("APB 25") and related Intrepretations in accounting for its plans.
Accordingly, no compensation cost has been recognized for its stock option
plans as the exercise price of all stock options granted thereunder is equal
to the fair value at the date of grant. Had compensation costs for the
Company's stock-based compensation plans been determined based on the fair
value at the grant dates for awards under those plans consistent with the
method of Financial Accounting Standards Board Statement No. 123, the
Company's net income and earnings per share would have been reduced to the pro
forma amounts indicated below:

  The fair value of each option grant is estimated on the date of grant using
the Black- Scholes option-pricing model with the following assumptions for
grants in 1996: no dividend yield; expected volatility of 40.8%; risk-free
interest rate of 6.2%; and expected life of 4 years. The following assumptions
were used for options granted in 1995: no dividend yield; expected volatility
of 41.6%; risk-free interest rate of 6.0%; and expected life of 4 years.

  The Amended and Restated Newpark Resources, Inc. 1988 Incentive Stock Option
Plan (the "1988 Plan") was adopted by the Board of Directors on June 22, 1988
and thereafter was approved by the stockholders. The 1988 Plan was amended and
restated by the Board of Directors and stockholders in 1992 to increase the
number of shares of Common Stock issuable thereunder from 420,000 to
1,890,000; was further amended by the Board of Directors and stockholders in
1994 to increase the number of shares of Common Stock issuable thereunder from
1,890,000 to 2,730,000, and was further amended by the Board of Directors and
stockholders in 1995 to increase the number of shares of Common Stock issuable
thereunder from 2,730,000 to four million shares. An option may not be granted
for an exercise price less than the fair market value on the date of grant and
may have a term of up to ten years.
 
  The 1992 Directors' Stock Option Plan (the "1992 Directors' Plan") was
adopted on October 21, 1992 by the Compensation Committee and, thereafter, was
approved by the stockholders in 1993.
 
  The purpose of the 1992 Directors' Plan was to provide two directors
("Optionees") additional compensation for their services to Newpark and to
promote an increased incentive and personal interest in the welfare of Newpark
by such directors. The Optionees were each granted a stock option to purchase
210,000 shares of Common Stock at an exercise price of $2.08 per share, the
fair market value of the Common Stock on the date of grant for a term of ten
years. No additional options may be granted under the Directors' Plan. At
December 31, 1996, all options had been exercised under this plan.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The 1993 Non-Employee Directors' Stock Option Plan (the "1993 Non-Employee
Directors' Plan") was adopted on September 1, 1993 by the Board of Directors
and, thereafter, was approved by the stockholders in 1994. Non-employee
directors are not eligible to participate in any other stock option or similar
plan currently maintained by Newpark. The purpose of the 1993 Non-Employee
Directors' Plan is to promote an increased incentive and personal interest in
the welfare of Newpark by those individuals who are primarily responsible for
shaping the long-range plans of Newpark, to assist Newpark in attracting and
retaining on the Board persons of exceptional competence and to provide
additional incentives to serve as a director of Newpark.
 
  Upon the adoption of the 1993 Non-Employee Directors' Plan, the five non-
employee directors were each granted a stock option to purchase 63,000 shares
of Common Stock at an exercise price of $2.14 per share, the fair market value
of the Common Stock on the date of grant. In addition, each new Non-Employee
Director, on the date of his or her election to the Board of Directors
automatically will be granted a stock option to purchase 63,000 shares of
Common Stock at an exercise price equal to the fair market value of the Common
Stock on the date of grant. The determination of fair market value of the
Common Stock is based on market quotations. On November 2, 1995, the Board of
Directors adopted, and the stockholders approved on June 12, 1996, amendments
to the Non-Employee Directors' Plan to increase the maximum number of shares
issuable thereunder from 630,000 to 840,000 and to provide for the automatic
grant at five year intervals of additional stock options to purchase 42,000
shares of Common Stock to each non-employee director who continues to serve on
the Board. At December 31, 1996, 105,000 options had been exercised under the
1993 Non-Employee Directors' Plan.
 
  On November 2, 1995, the Board of Directors adopted, and on June 12, 1996
the stockholders approved, the Newpark Resources, Inc. 1995 Incentive Stock
Option Plan (the "1995 Plan"), pursuant to which the Compensation Committee
may grant incentive stock options and nonstatutory stock options to designated
employees of Newpark. Initially, a maximum of 2,100,000 shares of Common Stock
may be issued under the 1995 Plan, with such maximum number increasing on the
last business day of each fiscal year of Newpark, commencing with the last
business day of the fiscal year ending December 31, 1996, by a number equal to
1.25% of the number of shares of Common Stock issued and outstanding on the
close of business on such date, with a maximum number of shares of Common
Stock that may be issued upon exercise of options granted under the 1995 Plan
being limited to 5,250,000. At December 31, 1996 there were 1,584,000 options
outstanding under the 1995 plan, 168,000 of which were exercisable.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Interest of $4,217,000, $4,290,000 and $2,713,000, was paid in 1996, 1995

respectively and income taxes of $4,151,000 and $3,163,000 were paid during
the nine months ended September 30, 1997, and 1996, respectively.
 
J. COMMITMENTS AND CONTINGENCIES
 
  Newpark and its subsidiaries are involved in litigation and other claims or
assessments on matters arising in the normal course of business. In the
opinion of management, any recovery or liability in these matters will not
have a material adverse effect on Newpark's consolidated financial statements.
 
  In conjunction with the closing of the Campbell acquisition, the Company
acquired Disposeco, thereby assuming the obligations provided in the "NOW
Disposal Agreement" between Disposeco and Campbell. The NOW Disposal Agreement
provides that for each of the 25 years following the closing, Newpark will
deliver to Campbell for disposal at its landfarms the lesser of one-third of
the barrels from a defined market area or 1,850,000 barrels of NOW, subject to
certain adjustments. The initial price per barrel to be paid by Newpark to
Campbell is $5.50 per barrel and is subject to adjustment in future years.
Prior to any adjustments, Newpark's obligation is $10,175,000 annually. In
addition, the liability of Newpark under the agreement is reduced by certain
prohibited revenues earned by Campbell or Sanifill.
 
  During 1992, the State of Texas assessed additional sales taxes for the
years 1988-1991. The Company has filed a petition for redetermination with the
Comptroller of Public Accounts. The Company believes that the ultimate
resolution of this matter will not have a material adverse effect on the
consolidated financial statements.
 
  In the normal course of business, in conjunction with its insurance
programs, the Company has established letters of credit in favor of certain
insurance companies in the amount of $1,650,000 at September 30, 1997, and
$1,750,000 and $2,825,000 at December 31, 1996 and 1995, respectively. At
September 30, 1997, and December 31, 1996 the Company had outstanding guaranty
obligations totaling $865,000 respectively, in connection with facility
closure bonds issued by an insurance company. At December 31, 1995, such
outstanding guaranty obligations totaled $469,000.
 
  Since May 1988, the Company has held the exclusive right to use a patented
prefabricated mat system with respect to the oil and gas exploration and
production industry within the State of Louisiana. On June 20, 1994, the
Company entered into a new license agreement by which it obtained the
exclusive right to use the same patented prefabricated mat system, without
industry restriction, throughout the continental United States. The license
agreement requires, among other things, that the company purchase a minimum of
20,000 mats annually through 2003. The Company has met this annual mat
purchase requirement since the inception of the agreement. Any purchases in
excess of that level may be applied to future annual requirements. The
Company's annual commitment to maintain the agreement in force is currently
estimated to be $4,600,000.
 
  On August 29, 1996, the Company sold the land, buildings and certain
equipment comprising substantially all of the assets of its former marine
repair operation to the operator of the facility. These assets had previously
been subject to an operating lease to the same party, and the purchase was
made under the terms of a purchase option granted in the original lease. The
Company has guaranteed certain of the debt obligations of the operator, which
is limited to a maximum of $10 million and reduces proportionately with debt
repayments made by the operator.
 
  At December 31, 1995, the Company had outstanding a letter of credit in the
amount of $3,816,000 issued to a state regulatory agency to assure funding for
future site closure obligations at its NORM processing facility.

                            NEWPARK RESOURCES, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company leases various manufacturing facilities, warehouses, office
space, machinery and equipment and transportation equipment under operating
leases with remaining terms ranging from one to ten years with various renewal
options. Substantially all leases require payment of taxes, insurance and
maintenance costs in addition to rental payments. Total rental expenses for all
operating leases were $5,251,000, $5,253,000, and $4,090,000, in 1996, 1995 and
1994, respectively.
 
  Future minimum payments under noncancelable operating leases, with initial or
remaining terms in excess of one year are: $3,093,000 in 1997, $2,581,000 in
1998, $2,402,000 in 1999, $2,233,000 in 2000, $1,548,000 in 2001, and
$1,070,000 thereafter.
 
  Capital lease commitments are not significant.
 
K. BUSINESS AND CREDIT CONCENTRATION
 
  During 1996 two customers each accounted for greater than 10% of revenues.
One customer accounted for approximately 16% and 15%, $21,620,000 and
$15,890,000, of total revenues for 1996 and 1995, respectively. The other
customer accounted for 9.4%, or $12,836,000, of revenues for 1996. In 1994, the
Company did not derive ten percent or more of its revenues from sales to any
single customer.
 
  Export sales are not significant.
 
L. CONCENTRATIONS OF CREDIT RISK
 
  Financial instruments which potentially subject the Company to significant
concentrations of credit risk consist principally of cash investments and trade
accounts and notes receivable.
 
  The Company maintains cash and cash equivalents with various financial
institutions. These financial institutions are located throughout the Company's
trade area and company policy is designed to limit exposure to any one
institution. As part of the Company's investment strategy, the Company performs
periodic evaluations of the relative credit standing of these financial
institutions.
 
  Concentrations of credit risk with respect to trade accounts and notes
receivable are limited due to the large number of entities comprising the
Company's customer base, and for notes receivable, the required collateral. The
Company maintains an allowance for losses based upon the expected
collectibility of accounts and notes receivable.

               PART II - INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the General Corporation Law of the State of Delaware (the
"GCL") permits a corporation to, and the registrant's bylaws require that it,
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation), by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with such action,
suit or proceeding if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

     As permitted under Section 145 of the GCL, the registrant's bylaws also
provide that it shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation. However, in such an action by or on behalf of a corporation, no
indemnification may be made in respect of any claim, issue or matter as to which
the person is adjudged liable for negligence or misconduct in the performance of
his duty to the corporation unless, and only to the extent that the court
determines that, despite the adjudication of liability but in view of all the
circumstances, the person is fairly and reasonably entitled to indemnity for
such expenses which the court shall deem proper.

     In addition, the indemnification provided by section 145 shall not be
deemed exclusive of any other rights to which a person seeking indemnification
may be entitled under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.

     The registrant's Certificate of Incorporation (the "Certificate") provides
that the registrant shall indemnify, to the fullest extent permitted by law,
each of its officers, directors, employees and agents who was or is a party to,
or is threatened to be made a party to, any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director,
officer, employee or agent of the registrant.  The Certificate also provides
that, to the fullest extent permitted by law, no director of the registrant
shall be liable to the registrant or its stockholders for monetary damages for
breach of his fiduciary duty as a director.

     The Certificate also provides that the registrant may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the registrant, or is serving at the request of the registrant as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise against any liability
incurred by such person in any such capacity, or arising out of his status as
such, regardless of whether the registrant is empowered to indemnify such person
under the provisions of law.  Newpark does not currently maintain any such
insurance.

ITEM 22.  UNDERTAKINGS

A.   The registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the Registration Statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, represent
a fundamental change in the information set forth in the Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more 

                                     II-2
<PAGE>
 
that a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective Registration Statement.

          (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement;

provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

B.   The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
related to the securities offered therein, and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

C.   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

D.   The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

                                     II-3
<PAGE>
 
E.   The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

     Section 103.  Compliance Certificates and Opinions.

     Upon any application or request by the Company to the Trustee to take any
action under any provision of this Indenture, the Company and any Guarantor (if
applicable) and any other obligor on the Securities (if applicable) shall
furnish to the Trustee an Officers' Certificate in a form and substance
reasonably acceptable to the Trustee stating that all conditions precedent, if
any, provided for in this Indenture (including any covenant compliance with
which constitutes a condition precedent) relating to the proposed action have
been complied with, and an Opinion of Counsel in a form and substance reasonably
acceptable to the Trustee stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that, in the case
of any such application or request as to which the furnishing of such
certificates or opinions is specifically required by any provision of this
Indenture relating to such particular application or request, no additional
certificate or opinion need be furnished.

                                       19
<PAGE>
 
     Every certificate or Opinion of Counsel with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

     (a) a statement that each individual signing such certificate or individual
or firm signing such opinion has read such covenant or condition and the
definitions herein relating thereto;

     (b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based;

     (c) a statement that, in the opinion of each such individual or such firm,
he or it has made such examination or investigation as is necessary to enable
him or it to express an informed opinion as to whether or not such covenant or
condition has been complied with; and

     (d) a statement as to whether, in the opinion of each such individual or
such firm, such condition or covenant has been complied with.

     Section 104.  Form of Documents Delivered to Trustee.

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
person, or that they be so certified or covered by only one document, but one
such person may certify or give an opinion with respect to some matters and one
or more other such persons as to other matters, and any such person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an officer of the Company, any Guarantor or
other obligor on the Securities may be based, insofar as it relates to legal
matters, upon a certificate or opinion of, or representations by, counsel,
unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters
upon which his certificate or opinion is based are erroneous.  Any such
certificate or opinion may be based, insofar as it relates to factual matters,
upon a certificate or opinion of, or representations by, an officer or officers
of the Company, any Guarantor or other obligor on the Securities stating that
the information with respect to such factual matters is in the possession of the
Company, any Guarantor or other obligor on the Securities, unless such officer
or counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.  Opinions of Counsel required to be delivered to the Trustee may have
qualifications customary for opinions of the type required and counsel
delivering such Opinions of Counsel may rely on certificates of the Company or
government or other officials customary for opinions of the type required,
including certificates certifying as to matters of fact, including that various
financial covenants have been complied with.

     Any certificate or opinion of an officer of the Company, any Guarantor or
other obligor on the Securities may be based, insofar as it relates to
accounting matters upon a certificate or opinion of, or representations by, an
accountant or firm of accountants in the employ of the Company, unless such
officer knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate or opinion may be based are erroneous.  Any
certificate or opinion of any independent firm of public accountants filed with
the Trustee shall contain a statement that such firm is independent with respect
to the Company.

     Where any person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Section 105.  Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company.  Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments.  Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section 105.

     (b) The ownership of Securities shall be proved by the Security Register.

     (c) Any request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holder of any Security shall bind every future Holder of the
same Security or the Holder of every Security issued upon the transfer thereof
or in exchange there for or in lieu thereof, in respect of anything done,
suffered or omitted to be done by the Trustee, any Paying Agent or the Company,
any Guarantor or any other obligor of the Securities in reliance thereon,
whether or not notation of such action is made upon such Security.

     (d) The fact and date of the execution by any person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof.  Where such execution is
by a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

     (e) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so.  Notwithstanding Trust Indenture Act
Section 316(c), any such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such first solicitation is completed.

     If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on
such record date or their designated proxies shall be deemed to be Holders for
purposes of determining whether Holders of the requisite proportion of
Securities then Outstanding have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act
(or their duly designated proxies), and for this purpose the Securities then
Outstanding shall be computed as of such record date; provided that no such
request, demand, authorization, direction, notice, consent, waiver or other Act
by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after such record date.

     Section 106.  Notices, etc., to the Trustee, the Company and any Guarantor.

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with:

     (a) the Trustee by any Holder or by the Company or any Guarantor or any
other obligor on the Securities shall be sufficient for every purpose (except as
provided in Section 501(c)) hereunder if in writing and mailed, first-class
postage prepaid, or delivered by a nationally recognized overnight courier, to
or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Department (Newpark Resources, Inc. 8 5/8% Senior Subordinated Notes due 2007),
or at any other address previously furnished in writing to the Holders, the
Company, any Guarantor or any other obligor on the Securities by the Trustee; or

     (b) the Company or any Guarantor by the Trustee or any Holder shall be
sufficient for every purpose (except as provided in Section 501(c)) hereunder if
in writing and mailed, first-class postage prepaid, or delivered by a nationally
recognized overnight courier, to the Company or such Guarantor addressed to it
c/o Newpark Resources, Inc., 3850 North Causeway Boulevard, Suite 1770,
Metairie, Louisiana 70002-1752, Attention: Chief Financial Officer, or at any
other address previously furnished in writing to the Trustee by the Company or
such Guarantor.

     Any notice required hereunder to be delivered to the lenders under the
Credit Facility shall be sufficient for every purpose hereunder if in writing
and mailed, first-class post,age prepaid or delivered by a nationally recognized
courier, to the Administrative Agent at Bank One, Louisiana, National
Association, 200 West Congress Street, Lafayette, Louisiana 70502-3246,
Attention: Rose M. Miller, Vice President, Facsimile No. (318) 236-7888, with a
copy to Gardere & Wynne, L.L.P., 1601 Elm Street, Dallas, Texas 75201-4761,
Attention: Robert N. Rule, Jr., Facsimile No: (214) 999-4667.

     Section 107.  Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, or delivered by a
nationally recognized overnight courier, to each Holder affected by such event,
at its address as it appears in the Security Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.  Any notice when mailed to a Holder in the aforesaid manner shall
be conclusively deemed to have been received by such Holder whether or not
actually received by such Holder.  Where this Indenture provides for notice in
any manner, such notice may be waived in writing by the person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause, it shall be impracticable to mail notice of any event as
required by any provision of this Indenture, then any method of giving such
notice as shall be reasonably satisfactory to the Trustee shall be deemed to be
a sufficient giving of such notice.

     Section 108.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any provision
of the Trust Indenture Act or another provision which is required or deemed to
be included in this Indenture by any of the provisions of the Trust Indenture
Act, the provision or requirement of the Trust Indenture Act shall

                                       22
<PAGE>
 
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

     Section 109.  Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     Section 110.  Successors and Assigns.

     All covenants and agreements in this Indenture and the Securities by the
Company and the Guarantors, and all agreements of the Trustee in this Indenture,
shall bind their respective successors and assigns, whether so expressed or not.

     Section 111.  Separability Clause.

     In case any provision in this Indenture or in the Securities or Guarantees
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby, and a Holder shall have no claim therefor against any party
hereto.

     Section 112.  Benefits of Indenture.

     Nothing in this Indenture or in the Securities or Guarantees, express or
implied, shall give to any person (other than the parties hereto and their
successors hereunder, any Paying Agent, the Holders, the holders of Senior
Indebtedness and the holders of Senior Guarantor Indebtedness) any benefit or
any legal or equitable right, remedy or claim under this Indenture.

     Section 113.  GOVERNING LAW.

     THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING
EFFECT TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

     Section 114.  Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, Maturity or
Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal or premium, if any, need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on such Interest Payment Date or Redemption Date, or at
the Maturity or Stated Maturity and no interest shall accrue with respect to
such payment for the period from, and after, such interest Payment Date,
Redemption Date, Maturity or Stated Maturity, as the case may be, to the next
succeeding Business Day.

     Section 115.  Independence of Covenants.

     All covenants and agreements in this Indenture shall be given independent
effect so that if a particular action or condition is not permitted by any such
covenants, the fact that it would be permitted by an exception to, or be
otherwise within the limitations of, another covenant shall not avoid the
occurrence of a Default or an Event of Default if such action is taken or
condition exists.

     Section 116.  Schedules and Exhibits.

     All schedules and exhibits attached hereto are by this reference made a
part hereof with the same effect as if herein set forth in full.

     Section 117.  Counterparts.

     This Indenture may be executed in any number of counterparts, and by each
party hereto on a separate counterpart, each of which shall be deemed an
original; but all such counterparts shall together constitute but one and the
same instrument.

     Section 118.  Rules by Trustee and Agents.

     The Trustee may make reasonable rules for action by, or a meeting of,
Holders.  The Securities Registrar or Paying Agent may make reasonable rules for
its functions.

     Section 119.  No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or any Subsidiary of the Company.  Any such indenture,
loan or debt agreement may not be used to interpret this Indenture.

     Section 120.  No Recourse Against Others.

     A DIRECTOR, OFFICER, EMPLOYEE OR STOCKHOLDER, AS SUCH, OF THE COMPANY, ANY
GUARANTOR OR THE TRUSTEE, SHALL NOT HAVE ANY LIABILITY FOR ANY OBLIGATIONS OF
THE COMPANY, ANY GUARANTOR OR THE TRUSTEE, UNDER THIS INDENTURE OR THE
SECURITIES OR FOR ANY CLAIM BASED ON, IN RESPECT OF OR BY REASON OF, SUCH
OBLIGATIONS OR THEIR CREATION.  EACH HOLDER BY ACCEPTING A SECURITY WAIVES AND
RELEASES ALL SUCH LIABILITY.  THE WAIVER AND RELEASE ARE PART OF THE
CONSIDERATION FOR THE ISSUE OF THE SECURITIES AND THE GUARANTEES.

     Section 121.  Agent for Service; Submission to Jurisdiction; Waiver of
Immunities.

     By the execution and delivery of this Indenture, each of Company and the
Guarantors, (i) acknowledges that it has, by separate written instrument,
designated and appointed Corporation Trust System as its authorized agent upon
which process may be served in any suit, action or proceeding arising out of or
relating to the Securities or the Guarantees or this Indenture that may be
instituted in any Federal or State court in the State of New York, Borough of
Manhattan, or brought under Federal or State securities laws or brought by the
Trustee (whether in its individual capacity or in its capacity as Trustee
hereunder), and acknowledges that Corporation Trust System has accepted such
designation, (ii) submits to the jurisdiction of any such court in any such
suit, action or proceeding, and (iii) agrees that service of process upon
Corporation Trust System and written notice of said service to it (mailed or
delivered to its President at the principal office of the Company as specified
in Section 106), shall be deemed in every respect effective service of process
upon it in any such suit or proceeding.  Each of the Company and the Guarantors
further agrees to take any and all action, including the execution and filing of
any and all such documents and instruments as may be necessary to continue such
designation and appointment of Corporation Trust System in full force and effect
so long as this Indenture shall be in full force and effect; provided that each
of the Company and the Guarantors may and shall (to the extent Corporation Trust
System

                                       24
<PAGE>
 
ceases to be able to be served on the basis contemplated herein), by written
notice to the Trustee, designate such additional or alternative agents for
service of process under this Section 121 that (i) maintains an office located
in the Borough of Manhattan, The City of New York in the State of New York, (ii)
are either (x) counsel for the Company or (y) a corporate service company which
acts as agent for service of process for other Persons in the ordinary course of
its business and (iii) agrees to act as agent for service of process in
accordance with this Section 121.  Such notice shall identify the name of such
agent for process and the address of such agent for process in the Borough of
Manhattan, The City of New York, State of New York.  Upon the request of any
Holder, the Trustee shall deliver such information to such Holder.
Notwithstanding the foregoing, there shall, at all times, be at least one agent
for service of process for each of the Company and the Guarantors appointed and
acting in accordance with this Section 121.

     To the extent that any of the Company or Guarantors has or hereafter may
acquire any immunity from jurisdiction of any court or from any legal process
(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, each of the Company and the Guarantors hereby irrevocably waives such
immunity in respect of its obligations under this Indenture and the Securities
and the Guarantees to the maximum extent permitted by law.

                                  ARTICLE TWO

     Newpark Resources, Inc., a Delaware corporation (herein called the
"Company", which term includes any successor person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to ________
or registered assigns, the principal sum of_________ United States dollars [IF
THE SERIES A SECURITY IS A GLOBAL SECURITY, THEN INSERT THE FOLLOWING:, or such
other principal amount (which, when taken together with the principal amounts of
all other Outstanding Securities, shall not exceed $125,000,000 less the
principal amount of Securities redeemed by the Company in accordance with the
Indenture) as may be set forth by the Security Registrar on Appendix A hereto in
accordance with the Indenture,] on December 15, 2007, at the office or agency of
the Company referred to below, and to pay interest thereon from December 17,
1997, or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, semiannually on June 15 and December 15 in each year,
commencing June 15, 1998 at the rate of 8 5/8% per annum, subject to adjustments
as described in the second following paragraph, in United States dollars, until
the principal hereof is paid or duly provided for. Interest shall be computed on
the basis of a 360-day year comprised of twelve 30-day months.

     The Holder of this Series A Security is entitled to the benefits of the
Registration Rights Agreement among the Company, the Guarantors and the Initial
Purchasers, dated December 10, 1997, pursuant to which, subject to the terms and
conditions thereof, the Company and the Guarantors are obligated to consummate
the Exchange Offer pursuant to which the Holder of this Security (and the
related Guarantees) shall have the right to exchange this Security (and the
related Guarantees) for 8 5/8% Senior Subordinated Notes due 2007, Series B and
related guarantees (herein called the "Series B Securities") in like principal
amount as provided therein.  The Series A Securities and the Series B Securities
are together (including related Guarantees) referred to as the "Securities".
The Series A Securities rank pari passu in right of payment with the Series B
Securities.

     If either (a) the Exchange Offer Registration Statement is not filed with
the Commission on or prior to the 45th calendar day following the date of
original issue of the Series A Securities, (b) the Exchange Offer Registration
Statement has not been declared effective on or prior to the 105th calendar day
following the date of original issue of the Series A Securities or (c) the
Exchange Offer is not consummated on or prior to the 135th calendar day
following the date of original issue of the Series A Securities or a Shelf
Registration Statement is not declared effective on or prior to the 135th
calendar day following the date of original issue of the Series A Securities
(each such event referred to in clauses (a) through (c) above, a "Registration
Default"), the interest rate borne by the Series A Securities shall be increased
("Additional Interest") by one-quarter of one percent per annum upon the
occurrence of each Registration Default, which rate (as increased as aforesaid)
will increase by one quarter of one percent each 90-day period that such
Additional Interest continues to accrue under any such circumstance, provided
that the maximum aggregate increase in the interest rate will in no event exceed
one percent (1%) per annum, including any increases pursuant to the provisions
of the following paragraph.  Following the cure of all Registration Defaults the
accrual of Additional Interest will cease and the interest rate will revert to
the original rate; provided, however, that, if after any such reduction in
interest rate, a different event specified in clause (a), (b) or (c) above
occurs, the interest rate shall again be increased pursuant to the foregoing
provisions.

                                       28
<PAGE>
 
     If the Shelf Registration Statement is unusable by the Holders for any
reason, and the aggregate number of days in any consecutive twelve-month period
for which the Shelf Registration Statement shall not be usable exceeds 30 days
in the aggregate, then the interest rate borne by the Securities held by such
Holders will be increased by 0.25% per annum of the principal amount of the
Securities for the first 90-day period (or portion thereof) beginning on the
31st such date that such Shelf Registration Statement ceases to be usable, which
rate shall be increased by an additional 0.25% per annum of the principal amount
of the Securities at the beginning of each subsequent 90-day period provided
that the maximum aggregate increase in the interest rate will in no event exceed
one percent (1%) per annum, including any increases pursuant to the provisions
of the preceding paragraph.  Any amounts payable under this paragraph shall also
be deemed "Additional Interest" for purposes of this Security.  Upon the Shelf
Registration Statement once again becoming usable, the interest rate borne by
the Securities will be reduced to the original interest rate if the Company is
otherwise in compliance with this Agreement at such time.  Additional Interest
shall be computed based on the actual number of days elapsed in each 90-day
period in which the Shelf Registration Statement is unusable.

     The Company shall notify the Trustee within three Business Days after each
and every date on which an event occurs in respect of which Additional Interest
is required to be paid (an "Event Date").  Additional Interest shall be paid by
depositing with the Trustee, in trust, for the benefit of the Holders of
Registrable Securities, on or before the applicable semiannual Interest Payment
Date, immediately available funds in sums sufficient to pay the Additional
Interest then due.  The Additional Interest due shall be payable on each
Interest Payment Date to the record Holder of Securities entitled to receive the
interest payment to be paid on such date as set forth in the Indenture.  Each
obligation to pay Additional Interest shall be deemed to accrue from and
including the day following the applicable Event Date.

     The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in such Indenture, be paid to the person
in whose name this Security (or any Predecessor Security) is registered at the
close of business on the Regular Record Date for such interest, which shall be
the June 1 or December 1 (whether or not a Business Day), as the case may be,
next preceding such Interest Payment Date.  Any such interest not so punctually
paid, or duly provided for, and interest on such defaulted interest at the
interest rate borne by the Series A Securities, to the extent lawful, shall
forthwith cease to be payable to the Holder on such Regular Record Date, and may
either be paid to the person in whose name this Security (or any Predecessor
Security) is registered at the close of business on a Special Record Date for
the payment of such defaulted interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities not less than 10 days prior to
such Special Record Date or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in this Indenture.

     Payment of the principal of, premium, if any, and interest on, this
Security, and exchange or transfer of the Security, will be made at the office
or agency of the Company in The City of New York maintained for that purpose, or
at such other office or agency as may be maintained for such purpose, in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.  Payment of interest will
be made (i) in respect of Securities held by the Depositary or its nominee, in
same day funds on or prior to the respective Interest Payment Dates and (ii) in
respect of Securities held of record by Holders other than the Depositary or its
nominee, in same day funds at the office of the Trustee in New York, New York or
at such other office or agency of the Company as it shall maintain for that
purpose pursuant to Section 1002; provided, however, that, at the option of the
Company, interest on any Security held of record by Holders other than the
Depositary or its nominee may be paid by mailing checks to the addresses of the
Holders thereof as such address appear in the Security Register.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     This Security is entitled to the benefits of Guarantees by each of the
Guarantors of the punctual payment when due of the Indenture Obligations made in
favor of the Trustee for the benefit of the Holders.  Reference is hereby made
to Article Fourteen of the Indenture for a statement of the respective rights,
limitations of rights, duties and obligations under the Guarantees of each of
the Guarantors.

     Unless the certificate of authentication hereon has been duly executed by
the Trustee referred to on the reverse hereof or by the authenticating agent
appointed as provided in the Indenture by manual signature of an authorized
signer, this Security shall not be entitled to any benefit under the Indenture,
or be valid or obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by the manual or facsimile signature of its authorized officers.

Series A Security, interest at such increased interest rate, if any, on this
Series B Security shall accrue from the most recent Interest Payment Date to
which such interest on the Series A Security has been paid or duly provided for;
provided, however,

                                       34
<PAGE>
 
that, if after any such reduction in interest rate, a different event specified
in clause (a), (b) or (c) above occurs, the interest rate shall again be
increased pursuant to the foregoing provisions.

     If the Shelf Registration Statement is unusable by the Holders for any
reason, and the aggregate number of days in any consecutive twelve-month period
for which the Shelf Registration Statement shall not be usable exceeds 30 days
in the aggregate then the interest rate borne by the Securities held by such
Holders will be increased by 0.25% per annum of the principal amount of the
Securities for the first 90-day period (or portion thereof) beginning on the
31st such date that such Shelf Registration Statement ceases to be usable, which
rate shall be increased by an additional 0.25% per annum of the principal amount
of the Securities at the beginning of each subsequent 90-day period, provided
that the maximum aggregate increase in the interest rate will in no event exceed
one percent (1%) per annum, including any increases pursuant to the provisions
of the preceding paragraph.  Any amounts payable under this paragraph shall also
be deemed "Additional Interest" for purposes of this Security.  Upon the Shelf
Registration Statement once again becoming usable, the interest rate borne by
the Securities will be reduced to the original interest rate if the Company is
otherwise in compliance with this Agreement at such time.  Additional Interest
shall be computed based on the actual number of days elapsed in each 90-day
period in which the Shelf Registration Statement is unusable.

     The Company shall notify the Trustee within three Business Days after each
and every date on which an event occurs in respect of which Additional Interest
is required to be paid (an "Event Date").  Additional Interest shall be paid by
depositing with the Trustee, in trust, for the benefit of the Holders of
Registrable Securities, on or before the applicable semiannual Interest Payment
Date, immediately available funds in sums sufficient to pay the Additional
Interest then due.  The Additional Interest due shall be payable on each
Interest Payment Date to the record Holder of Securities entitled to receive the
interest payment to be paid on such date as set forth in the Indenture.  Each
obligation to pay Additional Interest shall be deemed to accrue from and
including the day following the applicable Event Date.

     The interest so payable and punctually paid or duly provided for, on any
interest Payment Date will, as provided in such Indenture, be paid to the person
in whose name this Security (or any Predecessor Security) is registered at the
close of business on the Regular Record Date for such interest, which shall be
the June 1 or December 1 (whether or not a Business Day) as the case may be,
next preceding such Interest Payment Date.  Any such interest not so punctually
paid, or duly provided for and interest on such defaulted interest at the
interest rate borne by the Series B Securities to the extent lawful, shall
forthwith cease to be payable to the Holder on such Regular Record Date, and may
either be paid to the person in whose name this Security (or any Predecessor
Security) is registered at the close of business on a Special Record Date for
the payment of such defaulted interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in this, Indenture.

     Payment of the principal of, premium, if any, and interest on, this
Security and exchange or transfer of the Security, will be made at the office or
agency of the Company in The City of New York maintained for such purpose, or at
such other office or agency as may be maintained for such purpose, in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.  Payment of interest will be
made (i) in respect of Securities held by the Depositary or its nominee, in same
day funds on or prior to the respective Interest Payment Dates and (ii) in
respect of Securities held of record by Holders other than the Depositary or its
nominee, in same day funds at the office of the Trustee in New York, New York or
at such other office or agency of the Company as it shall maintain for that
purpose pursuant to Section 1002, provided, however, that, at the option of the
Company, interest on any Security held of record by Holders other than the
Depositary or its nominee may be paid by mailing checks to the addresses of the
Holders thereof as such addresses appear in the Security Register.

     Section 203.  Form of Reverse of Securities.

     (a) The form of the reverse of the Series A Securities shall be
substantially as follows:

                            NEWPARK RESOURCES, INC.
              8 5/8% Senior Subordinated Note due 2007, Series A

     This Security is one of a duly authorized issue of Securities of the
Company designated as its 8 5/8% Senior Subordinated Notes due 2007, Series A
(herein called the "Securities"), limited (except as otherwise provided in the
Indenture referred to below) in aggregate principal amount to $125,000,000,
issued under and subject to the terms of an indenture (herein called the
"Indenture") dated as of December 17, 1997, among the Company, the Guarantors
and State Street Bank and Trust Company, as trustee (herein called the
"Trustee," which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties,
obligations and immunities thereunder of the Company, the Guarantors, the
Trustee and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be authenticated and delivered.

     The Indenture contains provisions for defeasance at any time of (a) the
entire Indebtedness on the Securities and (b) certain restrictive covenants and
related Defaults and Events of Default, in each case upon compliance with
certain conditions set forth therein.

     The Securities are subject to redemption at any time on or after December
15, 2002 at the option of the Company, in whole or in part, on not less than 30
nor more than 60 days' prior notice to the Holders by first-class mail, in
amounts of $1,000 or an integral multiple thereof, at the following redemption
prices (expressed as percentages of the principal amount), if redeemed during
the 12-month period beginning December 15 of the years indicated below:

                                           Redemption
                         Year                 Price
                         ----              -----------
                         2002               104.313%
                         2003               102.875%
                         2004               101.438%

and thereafter at 100% of the principal amount, in each case, together with
accrued and unpaid interest, if any, to but not including the Redemption Date
(subject to the rights of Holders of record on relevant Regular Record Dates or
Special Record Dates to receive interest due on an Interest Payment Date).

     At any time prior to December 1, 2000, the Company may, at its option, use
the net proceeds of one or more Public Equity Offerings to redeem up to an
aggregate of 35% of the aggregate principal amount of Securities originally
issued under the Indenture at a redemption price equal to 108.625% of the
aggregate principal amount thereof, plus accrued and unpaid interest thereon, if
any, to the Redemption Date; provided that at least $81.25 million aggregate
principal amount of the Securities remains outstanding immediately after the
occurrence of such redemption.  In order to effect the foregoing redemption, the
Company must mail a notice of redemption no later than 30 days after the closing
of the related Public Equity Offering and must consummate such redemption within
60 days of the closing of the Public Equity Offering.

     If less than all of the Securities are to be redeemed, the Trustee shall
select the Securities or portions thereof to be redeemed in compliance with any
applicable requirements of the principal national securities exchange, if any,
on which the Securities are listed or, if the Securities are not then listed on
a national securities exchange (or if the Securities are so listed but such
exchange does not impose

                                       38
<PAGE>
 
requirements with respect to the selection of debt securities for redemption),
on a pro rata basis, by lot or by such method as the Trustee in its sole
discretion shall deem fair and appropriate.

     Upon the occurrence of a Change of Control, the Company shall be obligated
to make an offer to purchase, and subject to provisions of Section 1011 of the
Indenture, must purchase, all Outstanding Securities at a purchase price in cash
in an amount equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the date of purchase, pursuant to a Change of
Control Offer in accordance with the procedures set forth in the Indenture.

     Under certain circumstances, if the Net Cash Proceeds received by the
Company from any Asset Sale, which proceeds are not used to repay Senior
Indebtedness or invested in properties and assets that were the subject of the
Asset Sale or which will be used in the business of the Company or its
Subsidiaries existing on the date of the Indenture or in businesses reasonably
related thereto, exceeds a specified amount, the Company will be required to
apply such proceeds to the repurchase of the Securities and certain Indebtedness
ranking pari passu in right of payment to the Securities.

     In the case of any redemption or repurchase of Securities in accordance
with the Indenture, interest installments whose Stated Maturity is on or prior
to the Redemption Date will be payable to the Holders of such Securities of
record as of the close of business on the relevant Regular Record Date or
Special Record Date referred to on the face hereof.  Securities (or portions
thereof) for whose redemption and payment provision are made in accordance with
the Indenture shall cease to bear interest from and after the Redemption Date.

     In the event of redemption or repurchase of this Security in accordance
with the Indenture in part only, a new Security or Securities for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the
cancellation hereof.

     If an Event of Default shall occur and be continuing, the principal amount
of all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

     The Indenture permits with certain exceptions (including certain amendments
permitted without the consent of any Holders) as therein provided, the amendment
thereof and the modification of the rights and obligations of the Company and
the Guarantors and the rights of the Holders under the Indenture and the
Securities and the Guarantees at any time by the Company and the Trustee with
the consent of the Holders of a specified percentage in aggregate principal
amount of the Securities at the time Outstanding.  The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, to waive compliance by the Company and the
Guarantors with certain provisions of the Indenture and the Securities and the
Guarantees and certain past Defaults under the Indenture and the Securities and
the Guarantees and their consequences.  Any such consent or waiver by or on
behalf of the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this
Security.

     The Series A Securities are, to the extent and manner provided in Article
Thirteen of the Indenture, subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, any
Guarantor or any other obligor on the Securities (if such Guarantor or such
other obligor is obligated to make payments in respect of the Securities), which
is absolute and unconditional, to pay the principal of, premium, if any, and
interest on, this Security at

                                       39
<PAGE>
 
the times, place and rate, and in the coin or currency, herein prescribed,
subject to the subordination provisions of the Indenture.

     If this Series A Security is in certificated form, then as provided in the
Indenture and subject to certain limitations therein set forth, the transfer of
this Security is registrable on the Security Register of the Company, upon
surrender of this Security for registration of transfer at the office or agency
of the Company maintained for such purpose in The City of New York or at such
other office or agency of the Company as may be maintained for such purpose,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or its attorney duly authorized in writing, and thereupon one or
more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     If this Series A Security is in certificated form, then as provided in the
Indenture and subject to certain limitations therein set forth, the Holder,
provided it is a "Qualified Institutional Buyer" within the meaning of Rule 144A
under the Securities Act or a Non-U.S. Person, may exchange this Series A
Security for a Book-Entry Security by instructing the Trustee (by completing the
Transferee Certificate in the form in Appendix I) to arrange for such Series A
Security to be represented by a beneficial interest in a Rule 144A Global
Security or a Regulation S Global Security, as the case may be, in accordance
with the customary procedures of the Depository, unless the Company has elected
not to issue a Rule 144A Global Security or a Regulation S Global Security, as
the case may be.

     If this Series A Security is a Rule 144A Global Security, it is
exchangeable for a Series A Security in certificated form as provided in the
Indenture and in accordance with the rules and procedures of the Trustee and the
Depositary.  In addition, certificated securities shall be transferred to all
beneficial holders in exchange for their beneficial interests in the Rule 144A
Global Securities or the Regulation S Global Securities if (x) the Depositary
notifies the Company that it is unwilling or unable to continue as depository
for such Global Security and a successor depositary is not appointed by the
Company within 90 days or (y) there shall have occurred and be continuing an
Event of Default and the Security Registrar has received a request from the
Depositary.  Upon any such issuance, the Trustee is required to register such
certificated Series A Securities in the name of, and cause the same to be
delivered to, such person or persons (or the nominee of any thereof).  All such
certificated Series A Securities would be required to include the Private
Placement Legend.

     Series A Securities in certificated form are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof.  As provided in the Indenture and subject to certain limitations
therein set forth, the Series A Securities are exchangeable for a like aggregate
principal amount of Securities of a differing authorized denomination, as
requested by the Holder surrendering the same.

     At any time when the Company is not subject to Sections 13 or 15(d) of the
Exchange Act, upon the written request of a Holder of a Series A Security, the
Company will promptly furnish or cause to be furnished such information as is
specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor
provision thereto) to such Holder or to a prospective purchaser of such Series A
Security who such Holder informs the Company is reasonably believed to be a
"Qualified Institutional Buyer" within the meaning of Rule 144A under the
Securities Act, as the case may be, in order to permit compliance by such Holder
with Rule 144A under the Securities Act.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax, assessment or other governmental charge payable in connection
therewith.

                                       40
<PAGE>
 
     Prior to due presentment of this Security for registration of transfer, the
Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor
or the Trustee may treat the person in whose name his Security is registered as
the owner hereof for all purposes, whether or not this Security is overdue, and
neither the Company, any Guarantor, the Trustee nor any such agent shall be
affected by notice to the contrary.

     A DIRECTOR, OFFICER, EMPLOYEE OR STOCKHOLDER, AS SUCH, OF THE COMPANY, ANY
GUARANTOR OR THE TRUSTEE, SHALL NOT HAVE ANY LIABILITY FOR ANY OBLIGATIONS OF
THE COMPANY, ANY GUARANTOR OR THE TRUSTEE, UNDER THE INDENTURE OR THIS SECURITY
OR FOR ANY CLAIM BASED ON, IN RESPECT OF OR BY REASON OF, SUCH OBLIGATIONS OR
THEIR CREATION. EACH HOLDER BY ACCEPTING THIS SECURITY WAIVES AND RELEASES ALL
SUCH LIABILITY. THE WAIVER AND RELEASE ARE PART OF THE CONSIDERATION FOR THE
ISSUE OF THE SECURITIES AND THE GUARANTEES.

     THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES
THEREOF.

     All terms used in this Security which are defined in the Indenture and not
otherwise defined herein shall have the meanings assigned to them in the
Indenture.

     [The Transferee Certificate, in the Form of Appendix I hereto, will be
attached to the Series A Security.]

     (b) The form of the reverse of the Series B Securities shall be
substantially as follows:

                            NEWPARK RESOURCES, INC.
              8 5/8% Senior Subordinated Note due 2007, Series B


     This Security is one of a duly authorized issue of Securities of the
Company designated as its 8 5/8% Senior Subordinated Notes due 2007, Series B
(herein called the "Securities"), limited (except as otherwise provided in the
Indenture referred to below) in aggregate principal amount to $125,000,000,
issued under and subject to the terms of an indenture (herein called the
"Indenture") dated as of December 17, 1997, among the Company, the Guarantors
and State Street Bank and Trust Company, as trustee (herein called the
"Trustee," which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties,
obligations and immunities thereunder of the Company, the Guarantors, the
Trustee and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

     The Indenture contains provisions for defeasance at any time of (a) the
entire Indebtedness on the Securities and (b) certain restrictive covenants and
related Defaults and Events of Default, in each case upon compliance with
certain conditions set forth therein.

     The Securities are subject to redemption at any time on or after December
15, 2002, at the option of the Company, in whole or in part, on not less than 30
nor more than 60 days' prior notice to the Holders by first-class mail, in
amounts of $1,000 or an integral multiple thereof, at the following redemption
prices (expressed as percentages of the principal amount), if redeemed during
the 12-month period beginning December 15 of the years indicated below:

<PAGE>
 
                                                Redemption
                         Year                      Price
                         ----                      -----
                         2002                     104.313%
                         2003                     102.875%
                         2004                     101.438%

and thereafter at 100% of the principal amount, in each case, together with
accrued and unpaid interest, if any, to but not including the Redemption Date
(subject to the rights of Holders of record on relevant Regular Record Dates or
Special Record Dates to receive interest due on an Interest Payment Date).

     At any time prior to December 1, 2000, the Company may, at its option, use
the net proceeds of one or more Public Equity Offerings to redeem up to an
aggregate of 35% of the aggregate principal amount of Securities originally
issued under the Indenture at a redemption price equal to 108.625% of the
aggregate principal amount thereof, plus accrued and unpaid interest thereon, if
any, to the Redemption Date; provided that at least $81.25 million aggregate
principal amount of the Securities remains outstanding immediately after the
occurrence of such redemption.  In order to effect the foregoing redemption, the
Company must mail a notice of redemption no later than 30 days after the closing
of the related Public Equity Offering and must consummate such redemption within
60 days of the closing of the Public Equity Offering.

     If less than all of the Securities are to be redeemed, the Trustee shall
select the Securities or portions thereof to be redeemed in compliance with any
applicable requirements of the principal national securities exchange, if any,
on which the Securities are listed or, if the Securities are not then listed on
a national securities exchange (or if the Securities are so listed but such
exchange does not impose requirements with respect to the selection of debt
securities for redemption), on a pro rata basis, by lot or by such method as the
Trustee in its sole discretion shall deem fair and appropriate.

     Upon the occurrence of a Change of Control, the Company shall be obligated
to make an offer to purchase, and subject to provisions of Section 1011 of the
Indenture, must purchase, all Outstanding Securities at a purchase price in cash
in an amount equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the date of purchase, pursuant to a Change of
Control Offer in accordance with the procedures set forth in the Indenture.

     Under certain circumstances, if the Net Cash Proceeds received by the
Company from any Asset Sale, which proceeds are not used to repay Senior
Indebtedness or invested in properties and assets that were the subject of the
Asset Sale or which will be used in the business of the Company or its
Subsidiaries existing on the date of the Indenture or in businesses reasonably
related thereto, exceeds a specified amount the Company will be required to
apply such proceeds to the repurchase of the Securities and certain Indebtedness
ranking pari passu in right of payment to the Securities.

     In the case of any redemption or repurchase of Securities in accordance
with the Indenture, interest installments whose Stated Maturity is on or prior
to the Redemption Date will be payable to the Holders of such Securities of
record as of the close of business on the relevant Regular Record Date or
Special Record Date referred to on the face hereof.  Securities (or portions
thereof) for whose redemption and payment provision is made in accordance with
the Indenture shall cease to bear interest from and after the Redemption Date.

     In the event of redemption or repurchase of this Security in accordance
with the Indenture in part only, a new Security or Securities for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the
cancellation hereof.

     If an Event of Default shall occur and be continuing, the principal amount
of all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

                                       42

     The Indenture permits, with certain exceptions (including certain
amendments permitted without the consent of any Holders) as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantors and the rights of the Holders under the Indenture and
the Securities and the Guarantees at any time by the Company and the Trustee
with the consent of the Holders of a specified percentage in aggregate principal
amount of the Securities at the time Outstanding.  The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, to waive compliance by the Company and the
Guarantors with certain provisions of the Indenture and the Securities and the
Guarantees and certain past Defaults under the Indenture and the Securities and
the Guarantees and their consequences.  Any such consent or waiver by or on
behalf of the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this
Security.

     The Series B Securities are, to the extent and manner provided in Article
Thirteen of the Indenture, subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, any
Guarantor or any other obligor on the Securities (if such Guarantor or such
other obligor is obligated to make payments in respect of the Securities), which
is absolute and unconditional, to pay the principal of, and premium, if any, and
interest on, this Security at the times, place and rate, and in the coin or
currency, herein prescribed, subject to the subordination provisions of the
Indenture.

     If this Series B Security is in certificated form, then as provided in the
Indenture and subject to certain limitations therein set forth, the transfer of
this Series B Security is registrable on the Security Register of the Company,
upon surrender of this Series B Security for registration of transfer at the
office or agency of the Company maintained for such purpose in The City of New
York or at such other office or agency of the Company as may be maintained for
such purpose, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or its attorney duly authorized in writing, and
thereupon one or more new Series B Securities, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     If this Series B Security is in certificated form, then as provided in the
Indenture and subject to certain limitations therein set forth, the Holder may
exchange this Series B Security for a Book-Entry Security by instructing the
Trustee to arrange for such Series B Security to be represented by a beneficial
interest in a Series B Global Security in accordance with the customary
procedures of the Depository, unless the Company has elected not to issue a
Series B Global Security.

     If this Series B Security is a Series B Global Security, it is exchangeable
for a Series B Security in certificated form as provided in the Indenture and in
accordance with the rules and procedures of the Trustee and the Depositary.  In
addition, certificated securities shall be transferred to all beneficial holders
in exchange for their beneficial interests in the Series B Global Security if
(x) the Depositary notifies the Company that it is unwilling or unable to
continue as depository for the Series B Global Security and a successor
depositary is not appointed by the Company within 90 days or (y) there shall
have occurred and be continuing an Event of Default and the Security Registrar
has received a request from the Depositary.  Upon any such issuance, the Trustee
is required to register such certificated Series B Securities in the name of,
and cause the same to be delivered to, such person or persons (or the nominee of
any thereof).

                                       43

     Series B Securities in certificated form are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof.  As provided in the Indenture and subject to certain limitations
therein set forth, the Series B Securities are exchangeable for a like aggregate
principal amount of Securities of a differing authorized denomination, as
requested by the Holder surrendering the same.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax, assessment or other governmental charge payable in connection
therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor
or the Trustee may treat the person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security is overdue, and
neither the Company, any Guarantor, the Trustee nor any such agent shall be
affected by notice to the contrary.

     A DIRECTOR, OFFICER, EMPLOYEE OR STOCKHOLDER, AS SUCH, OF THE COMPANY, ANY
GUARANTOR OR THE TRUSTEE, SHALL NOT HAVE ANY LIABILITY FOR ANY OBLIGATIONS OF
THE COMPANY, ANY GUARANTOR OR THE TRUSTEE, UNDER THE INDENTURE OR THIS SECURITY
OR FOR ANY CLAIM BASED ON, IN RESPECT OF OR BY REASON OF, SUCH OBLIGATIONS OR
THEIR CREATION.  EACH HOLDER BY ACCEPTING THIS SECURITY WAIVES AND RELEASES ALL
SUCH LIABILITY.  THE WAIVER AND RELEASE ARE PART OF THE CONSIDERATION FOR THE
ISSUE OF THE SECURITIES AND THE GUARANTEES.

     THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES
THEREOF.

     All terms used in this Security which are defined in the Indenture and not
otherwise defined herein shall have the meanings assigned to them in the
Indenture.

                                 ARTICLE THREE

                                 THE SECURITIES

     Section 301.  Title and Terms.

     The aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is limited to $125,000,000 in principal amount of
Series A Securities and $125,000,000 in principal amount of Series B Securities,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section 303,
304, 305, 306, 307, 308, 906, 1011, 1012 or 1108.

     The Series A Securities shall be known and designated as the 8 5/8% Series
A Senior Subordinated Notes due 2007, Series A of the Company. The Stated
Maturity of the Series A Securities shall be December 15, 2007, and the Series A
Securities shall each bear interest, at the rate of 8 5/8% per annum, as such
interest rate may be adjusted as set forth in the Series A Security, from
December 17, 1997, or from the most recent Interest Payment Date to which
interest has been paid, as the case may be, payable semiannually on June 15 and
December 15, in each year commencing June 15, 1998, until the principal thereof
is paid or duly provided for. Interest on any overdue principal, interest (to
the extent lawful) or premium, if any, shall be payable on demand.

     The Series B Securities shall be known and designated as the 8 5/8% Series
B Senior Subordinated Notes due 2007, Series B of the Company. The Stated
Maturity of the Series B Securities shall be December 15, 2007, and the Series B
Securities shall each bear interest at the rate of 8 5/8% per annum, as such
interest rate may be adjusted as set forth in the Series B Security, from their
issuance date or from the most recent Interest Payment Date to which interest
has been paid, as the case may be, payable semiannually on June 15 and December
15, in each year commencing June 15, 1998, until the principal thereof is paid
or duly provided for. Interest on any overdue principal, interest (to the extent
lawful) or premium, if any, shall be payable on demand.

     The principal of and premium, if any, and interest on the Securities shall
be payable (i) in respect of Securities held of record by the Depositary or its
nominee in same day funds on or prior to the respective payment dates and (ii)
in respect of Securities held of record by Holders other than the Depositary or
its nominee in same day funds at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; provided, however, that at the option
of the Company, payment of interest to Holders of record other than the
Depositary may be made by check mailed to the address of the person entitled
thereto as such address shall appear in the Security Register.  The Securities
will be exchangeable and transferable at an office or agency of the Company in
The City of New York maintained for such purposes.

     For all purposes hereunder, the Series A Securities and the Series B
Securities will be treated as one class and are together referred to as the
"Securities."  The Series A Securities rank pari passu in right of payment with
the Series B Securities.

     The Securities shall be subject to repurchase by the Company pursuant to an
Offer as provided in Section 1012.

     The Company shall offer to purchase, and shall purchase all Outstanding
Securities, in the event of a Change of Control, pursuant to the terms of
Section 1011.

     The Securities shall be redeemable as provided in Article Eleven and in the
Securities.

                                       47
<PAGE>
 
     The Indebtedness evidenced by the Securities shall be subordinated in right
of payment to Senior Indebtedness as provided in Article Thirteen.

     At the election of the Company, the entire Indebtedness on the Securities
or certain of the Company's obligations and covenants and certain Events of
Default thereunder may be defeased as provided in Article Four.

     Section 302.  Denominations.

     The Securities shall be issuable only in fully registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

     Section 303.  Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by one of its
Chairman of the Board, its President, its Chief Executive Officer, its Chief
Financial Officer or one of its Vice Presidents attested by its Secretary or one
of its Assistant Secretaries.  The signatures of any of these officers on the
Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee (with Guarantees endorsed thereon) for authentication, together with a
Company Order for the authentication and delivery of such Securities; and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Securities as provided in this Indenture and not otherwise.

     Each Security shall be dated the date of its authentication.

     No Security or Guarantee endorsed thereon shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein duly executed by the Trustee by manual signature of an
authorized officer, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and is entitled to the benefits of this Indenture.

     In case the Company or any Guarantor, pursuant to Article Eight, shall, in
a single transaction or through a series of related transactions, be
consolidated or merged with or into any other person or shall sell, assign,
convey, transfer, lease or otherwise dispose of all or substantially all of its
properties and assets to any person, and the successor person resulting from
such consolidation or surviving such merger, or into which the Company or such
Guarantor shall have been merged, or the successor person which shall have
participated in the sale, assignment, conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Securities authenticated
or delivered prior to such consolidation, merger, sale, assignment, conveyance,
transfer, lease or other disposition may, from time to time, at the request of
the successor person, be exchanged for other Securities executed in the name of
the successor person with such changes in phraseology and form as may be
appropriate, but otherwise in substance of like tenor as the Securities
surrendered for such exchange and of like principal amount; and the Trustee,
upon Company Request of the successor person, shall authenticate and deliver
Securities as specified in such request for the purpose of such exchange.  If
Securities shall at any time be authenticated and delivered

                                       48
<PAGE>
 
in any new name of a successor person pursuant to this Section 303 in exchange
or substitution for or upon registration of transfer of any Securities, such
successor person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Securities on behalf of the Trustee.  Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so.  Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.  An
authenticating agent has the same rights as any Security Registrar or Paying
Agent to deal with the Company and its Affiliate.

     Section 304.  Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten or otherwise produced,
in any authorized denomination, substantially of the tenor of the definitive
Securities in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Securities may determine, as conclusively evidenced by their
execution of such Securities.  Every such temporary Security shall be executed
by the Company and shall be authenticated and delivered by the Trustee upon the
same conditions and in substantially the same manner, and with the same effect,
as the definitive Security or Securities in lieu of which it is issued.

     If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 1002,
without charge to the Holder.  Upon surrender for cancellation of any one or
more temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations.  Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

     Section 305.  Registration, Registration of Transfer and Exchange.

     The Company shall cause the Trustee to keep, so long as it is the Security
Registrar, at the Corporate Trust Office of the Trustee, or such other office as
the Trustee may designate, a register (the register maintained in such office or
in any other office or agency designated pursuant to Section 1002 being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as the Security Registrar may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee shall initially be the "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.  The
Company may appoint one or more co-Security Registrars.  At all reasonable times
the Security Register shall be open for inspection by the Company.

     Upon surrender for registration of transfer of any Security at the office
or agency of the Company designated pursuant to Section 1002, the Company shall
execute and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of any authorized denomination or denominations, of a like aggregate
principal amount.

     Furthermore, any Holder of a Global Security shall, by acceptance of such
Global Security, agree that transfers of beneficial interests in such Global
Security may be effected only through a book-entry system maintained by the
Holder of such Global Security (or its agent), and that ownership of a
beneficial interest in a Security shall be required to be reflected in a book
entry.

                                       49
<PAGE>
 
     At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denomination or denominations, of a like aggregate
principal amount, upon surrender of the Securities to be exchanged at such
office or agency.  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver,
Securities of the same series which the Holder making the exchange is entitled
to receive; provided that no exchange of Series A Securities for Series B
Securities shall occur until an Exchange Offer Registration Statement shall have
been declared effective by the Commission and that the Series A Securities
exchanged for the Series B Securities shall be canceled.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
Indebtedness, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer, or
for exchange, repurchase or redemption, shall (if so required by the Company or
the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made to a Holder for any registration of
transfer, exchange or redemption of Securities, except in certain circumstances
for any tax, assessment or other governmental charge that may be imposed in
connection therewith, other than exchanges pursuant to Sections 303, 304, 305,
308, 906, 1011, 1012 or 1108 not involving any transfer.

     Neither the Company nor the Security Registrar shall be required (a) to
issue, register the transfer of or exchange any Security during a period
beginning at the opening of business 15 days before the mailing of a notice of
redemption of the Securities selected for redemption under Section 1104 and
ending at the close of business on the day of such mailing, or (b) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part except the unredeemed portion of Securities being redeemed in part.

     Every Security shall be subject to the restrictions on transfer provided in
the legend required to be set forth on the face of each Security pursuant to
Section 202, and to the restrictions set forth in this Section 305, and the
Holder of each Security, by such Holder's acceptance thereof (or interest
therein), agrees to be bound by such restrictions on transfer.

     The restrictions imposed by this Section 305 upon the transferability of
any particular Security shall cease and terminate on (a) the later of December
17, 1999 or two years after the last date on which the Company or any Affiliate
of the Company was the owner of such Security (or any predecessor of such
Security) or (b) (if earlier) if and when such Security has been sold pursuant
to an effective registration statement under the Securities Act or transferred
pursuant to Rule 144 or Rule 904 under the Securities Act (or any successor
provision), unless the Holder thereof is an affiliate of the Company within the
meaning of Rule 144 (or such successor provisions).  Any Security as to which
such restrictions on transfer shall have expired, in accordance with their terms
or shall have terminated may, upon surrender of such Security for exchange to
the Security Registrar in accordance with the provision of this Section 305
(accompanied, if such restrictions on transfer have terminated pursuant to Rule
144 or Rule 904 (or any successor provision), by an Opinion of Counsel
satisfactory to the Company and the Trustee, to the effect that the transfer of
such Security has been made in compliance with Rule 144 or Rule 904 (or any such
successor provision)), be exchanged for a new Security of like tenor and
aggregate principal amount, which shall not bear the Private Placement Legend.
The Company shall inform the Trustee of the effective date of any Registration
Statement registering the Securities under the Securities Act no later than two
Business Days after such effective date.

                                       50

     Except as provided in the preceding paragraph, any Security authenticated
and delivered upon registration of transfer of, or in exchange for, or in lieu
of, any U.S. Global Security, whether pursuant to this Section 305, Section 304,
308, 906 or 1108 or otherwise, shall also be a U.S. Global Security and bear the
legend specified in Section 202.

     Section 306.  Book-Entry Provisions for Global Securities.

     (a) Each Global Security initially shall (i) be registered in the name of
the Depositary for such Global Security or the nominee of such Depositary, (ii)
be deposited with, or on behalf of, the Depositary or with the Trustee as
custodian for such Depositary and (iii) bear legends as set forth in Section
202.

          Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary, or the Trustee as its custodian, or under such
Global Security, and the Depositary may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner of such Global
Security for all purposes whatsoever.  Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or shall impair, as between the
Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Security.

     (b) Transfers of each Global Security shall be limited to transfers of such
Global Security in whole, but not in part, to the Depositary, its successors or
their respective nominees.  Interests of beneficial owners in each Global
Security may be transferred in accordance with the rules and procedures of the
Depositary and the provisions of Section 307.  Beneficial owners of interests in
the Rule 144A Global Securities and Series B Global Securities may obtain, in
certificated form, Securities in registered form without coupons (the "Physical
Securities") in exchange for their beneficial interests in the Rule 144A Global
Securities or Series B Global Securities, as applicable, upon request in

Security and a successor Depositary is not appointed by the Company within 90
days of such notice or (ii) an Event of Default has occurred and is continuing

     (c) In connection with any transfer of a portion of the beneficial interest

required to hold Physical Securities, the Security registrar shall reflect on
its books and records the date and a decrease in the principal amount of such
Global Security in an amount equal to the principal amount of the beneficial
interest in such Global Security to be transferred, and the Company shall
execute, and the Trustee shall authenticate and deliver, one or more Physical
Securities of like tenor and amount.

     (d) In connection with the transfer of an entire Global Security to

     (e) Any Physical Security constituting a "restricted security" within the
meaning of Rule 144(a)(3) under the Securities Act delivered in exchange for an
interest in a Global Security pursuant to Section 306(c) or Section 306(d)
shall, except as otherwise provided by Section 307, bear the Private Placement
Legend.

     (f) The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may

     Section 307.  Special Transfer Provisions.

     Unless and until (i) an Initial Security is sold under an effective
Registration Statement, or (ii) an Initial Security is exchanged for a Series B
Security in connection with the Exchange Offer, in each case pursuant to the
Registration Rights Agreement, the following provisions shall apply:

     (a) Transfers to QIBs.  The following provisions shall apply with respect
to the registration of any proposed transfer of an Initial Security to a QIB
(excluding Non-U.S. Persons):

          (i) The Security Registrar shall register the transfer of any Initial
     Security, whether or not such Security bears the Private Placement Legend
     if (x) the requested transfer is after the second anniversary of the Issue
     Date; provided, however, that neither the Company nor any Affiliate of the
     Company has held any beneficial interest in such Security, or portion
     thereof, at any time on or prior to the second anniversary of the Issue
     Date and such transfer can otherwise lawfully be made under the Securities
     Act without registering such Initial Security thereunder or (y) such
     transfer is being made by a proposed transferor who has checked the box
     provided for on the form of Initial Security stating, or has otherwise
     advised the Company and the Security Registrar in writing, that the sale
     has been made in compliance with the provisions of Rule 144A to the
     transferee who has signed the certification provided for on the form of
     Initial Security stating, or has otherwise advised the Company and the
     Security Registrar in writing,that it is purchasing the Initial Security
     for its own account or an account with respect to which it exercises sole
     investment discretion and that it, or the person on whose behalf it is
     acting with respect to any such account, is a QIB within the meaning of
     Rule 144A, and is aware that the sale to it is being made in reliance on
     Rule 144A and acknowledges that it has received such information regarding
     the Company as it has requested pursuant to Rule 144A or has determined not
     to request such information and that it is aware that the transferor is
     relying upon its foregoing representations in order to claim the exemption
     from registration provided by Rule 144A.

          (ii) If the proposed transferee is an Agent Member, and the Initial
     Security to be transferred consists of Physical Securities which after
     transfer are to be evidenced by an interest in the Rule 144A Global
     Security, upon receipt by the Security Registrar of instructions given in
     accordance with the Depositary's and the Security Registrar's procedures
     therefor, the Security Registrar shall reflect on Appendix A to the Rule
     144A Global Security the date and an increase in the principal amount of
     the Rule 144A Global Security in an amount equal to the principal amount of
     the Physical Securities to be transferred, and the Trustee shall cancel the
     Physical Security so transferred.

          (iii)  If the proposed transferor is an Agent Member seeking to
     transfer an interest in a Global Security, upon receipt by the Security
     Registrar of written instructions given in accordance with the Depositary's
     and the Security Registrar's procedures, the Security Registrar shall
     register the transfer and reflect (A) on Appendix A to Global Security from
     which interests are to be transferred the date and a decrease in the
     principal amount of the Global Security from which interests are to be
     transferred in an amount equal to the principal amount of the Securities to
     be transferred and (B) on Appendix A to the Rule 144A Global Security the
     date and an

                                       52
<PAGE>
 
     increase in the principal amount of the Rule 144A Global Security in an
     amount equal to the principal amount of the Global Security to be
     transferred.

     (b) Transfers to Non-U.S. Persons.  The following provisions shall apply
with respect to any transfer of an Initial Security to a Non-U.S. Person:

          (i) Prior to January 26, 1998, an owner of a beneficial interest in
     the Regulation S Global Security may not transfer such interest to a
     transferee that is a U.S. Person or for the account or benefit of a U.S.
     Person within the meaning of Rule 902(o) under the Securities Act.  During
     such time, all beneficial interests in the Regulation S Global Security
     shall be transferred only through Cedel or Euroclear, either directly if
     the transferor and transferee are participants in such system, or
     indirectly through organizations that are participants.

          (ii) The Security Registrar shall register the transfer of any Initial
     Security, whether or not such Security bears the Private Placement Legend,
     if (x) the proposed transferee has delivered to the Security Registrar a
     certificate substantially in the form of Exhibit B hereto or (y) the
     proposed transferor has delivered to the Security Registrar a certificate
     substantially in the form of Exhibit C hereto.

          (iii)  If the proposed transferee is an Agent Member and the
     Securities to be transferred consist of Physical Securities which after
     transfer are to be evidenced by an interest in the Regulation S Global
     Security, upon receipt by the Security Registrar of (x) written
     instructions given in accordance with the Depositary's and the Security
     Registrar's procedures and (y) the appropriate certificate required by
     clause (y) of paragraph (ii) of this Section 307(b), together with any
     required legal opinions and certifications, the Security Registrar shall
     register the transfer and reflect on Appendix A to the Regulation S Global
     Security the date and an increase in the principal amount of the Regulation
     S Global Security in an amount equal to the principal amount of Physical
     Securities to be transferred, and the Trustee shall cancel the Physical
     Securities so transferred.

          (iv) If the proposed transferor is an Agent Member seeking to transfer
     an interest in a Global Security, upon receipt by the Security Registrar of
     (x) written instructions given in accordance with the Depositary's and the
     Security Registrar's procedures and (y) the appropriate certificate
     required by clause (y) of paragraph (ii) of this Section 307(b), together
     with any required legal opinions and certificates, the Security Registrar
     shall register the transfer and reflect (A) on Appendix A to the Global
     Security from which interests are to be transferred the date and a decrease
     in the principal amount of the Global Security from which such interests
     are to be transferred in an amount equal to the principal amount of the
     Securities to be transferred and (B) on Appendix A to the Regulation S
     Global Security the date and an increase in the principal amount of the
     Regulation S Global Security in an amount equal to the principal amount of
     the Global Security to be transferred.

     (c)  Private Placement Legend.  Upon the registration of transfer, exchange
or replacement of Securities not bearing the Private Placement Legend, the
Security Registrar shall deliver Securities that do not bear the Private
Placement Legend.  Upon the registration of transfer, exchange or replacement of
Securities bearing the Private Placement Legend, the Security Registrar shall
deliver only Securities that bear the Private Placement Legend unless there is
delivered to the Security Registrar an Opinion of Counsel reasonably
satisfactory to the Company and the Trustee to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act.

     (d) General.  By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such a Security acknowledges the restrictions
on transfer of such Security set forth in this

                                       53
<PAGE>
 
Indenture and in the Private Placement Legend and agrees that it will transfer
such Security only as provided in this Indenture.

     The Security Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 306 or this Section
307.  The Company shall have the right, to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Security Registrar.

     If Regulation S is amended during the term of this Indenture to alter the
applicable holding period, all reference in this Indenture to a holding period
for Non-U.S. Persons will be deemed to include such amendment.

     Section 308.  Mutilated, Destroyed, Lost and Stolen Securities.

     If (a) any mutilated Security is surrendered to the Trustee, or (b) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, any Guarantor and the Trustee, such security or indemnity, in each
case, as may be required by them to save each of them harmless, then, in the
absence of notice to the Company, any Guarantor or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company and the
Guarantors shall execute and upon a Company Request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a replacement Security of like
tenor and principal amount, bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company or any Guarantor in its
discretion may, instead of issuing a replacement Security, pay such Security.

     Upon the issuance of any replacement Securities under this Section, the
Company may require the payment of a sum sufficient to pay all documentary,
stamp or similar issue or transfer taxes or other governmental charges that may
be imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

     Every replacement Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company and any Guarantor, and shall be entitled
to all benefits of this Indenture equally and proportionately with any and all
other Securities duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     Section 309.  Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on the Stated Maturity of such interest shall be paid to the
person in whose name the Security (or any Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest payment.
Payment of interest will be made (i) in respect of Securities held by the
Depositary or its nominee, in same day funds on or prior to the respective
Interest Payment Dates and (ii) in respect of Securities held of record by
Holders other than the Depositary or its nominee, in same day funds at the
office of the Trustee in New York, New York or at such other office or agency of
the Company as it shall maintain for that purpose pursuant to Section 1002;
provided, however, that, at the option of the Company, interest on any Security
held of record by Holders other than the Depositary or its nominee

                                       54
<PAGE>
 
may be paid by mailing checks to the addresses of the Holders thereof as such
addresses appear in the Security Register.

     Any interest on any Security which is payable, but is not punctually paid
or duly provided for, on the Stated Maturity of such interest, and interest on
such defaulted interest at the then applicable interest rate borne by the
Securities, to the extent lawful (such defaulted interest and interest thereon
herein collectively called "Defaulted Interest"), shall forthwith cease to be
payable to the Holder on the Regular Record Date; and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in
Subsection (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the
     persons in whose names the Securities (or any relevant Predecessor
     Securities) are registered at the close of business on a Special Record
     Date for the payment of such Defaulted Interest, which shall be fixed in
     the following manner.  The Company shall notify the Trustee in writing of
     the amount of Defaulted Interest proposed to be paid on each Security and
     the date (not less than 30 days after such notice) of the proposed payment
     (the "Special Payment Date"), and at the same time the Company shall
     deposit with the Trustee an amount of money equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit prior to the
     Special Payment Date, such money when deposited to be held in trust for the
     benefit of the persons entitled to such Defaulted Interest as in this
     Subsection provided.  Thereupon the Trustee shall fix a Special Record Date
     for the payment of such Defaulted Interest which shall be not more than 15
     days and not less than 10 days prior to the date of the Special Payment
     Date and not less than 10 days after the receipt by the Trustee of the
     notice of the proposed payment.  The Trustee shall promptly notify the
     Company in writing of such Special Record Date.  In the name and at the
     expense of the Company, the Trustee shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to each Holder at its address as it
     appears in the Security Register, not less than 10 days prior to such
     Special Record Date.  Notice of the proposed payment of such Defaulted
     Interest and the Special Record Date and Special Payment Date there for
     having been so mailed, such Defaulted Interest shall be paid to the persons
     in whose names the Securities are registered on such Special Record Date
     and shall no longer be payable pursuant to the following Subsection (b).

     (b) The Company may make payment of any Defaulted Interest in any other
     lawful manner not inconsistent with the requirements of any securities
     exchange on which the Securities may be listed, and upon such notice as may
     be required by such exchange, if, after written notice given by the Company
     to the Trustee of the proposed payment pursuant to this Subsection, such
     payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 309, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

     Section 310.  CUSIP Numbers.

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and the Company, or the Trustee on behalf of the Company,
shall use CUSIP numbers in notices of redemption or exchange as a convenience to
Holders; provided, however, that any such notice shall state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of redemption or exchange and
that reliance may be placed only on the other identification numbers printed on
the Securities; and provided further, however, that failure to use CUSIP numbers
in any notice of redemption or exchange shall not affect the validity or
sufficiency of such notice.

     Section 311.  Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the
Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor
or the Trustee may treat the person in whose name any Security is registered as
the owner of such Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 309) interest on, such Security and for
all other purposes whatsoever, whether or not such Security is overdue, and
neither the Company, any Guarantor, the Trustee nor any agent of the Company,
any Guarantor or the Trustee shall be affected by notice to the contrary.

     Section 312.  Cancellation.

     All Securities surrendered for payment, purchase, redemption, registration
of transfer or exchange shall be delivered to the Trustee and, if not already
canceled, shall be promptly canceled by it.  The Company and any Guarantor may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or such Guarantor may
have acquired in any manner whatsoever, and all Securities so delivered shall be
promptly canceled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section 312,
except as expressly permitted by this Indenture.  All canceled Securities held
by the Trustee shall be destroyed and certification of their destruction
delivered to the Company, unless by a Company Order received by the Trustee
prior to such destruction, the Company shall direct that the canceled Securities
be returned to it.  The Trustee shall provide the Company a list of all
Securities that have been canceled from time to time as requested by the
Company.

     Section 313.  Computation of Interest.

     Interest on the Securities shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.


                                  ARTICLE FOUR

                       DEFEASANCE AND COVENANT DEFEASANCE

     Section 401.  Company's Option to Effect Defeasance or Covenant Defeasance.

     The Company may, at its option by Board Resolution, at any time, with
respect to the Securities, elect to have either Section 402 or Section 403 be
applied to all of the Outstanding Securities (the "Defeased Securities"), upon
compliance with the conditions set forth below in this Article Four.

     Section 402.  Defeasance and Discharge.

     Upon the Company's exercise under Section 401 of the option applicable to
this Section 402, the Company, each Guarantor and any other obligor upon the
Securities, if any, shall be deemed to have been discharged from its obligations
with respect to the Defeased Securities on the date the conditions set forth in
Section 404 are satisfied (hereinafter, "defeasance").  For this purpose, such
defeasance means that the Company, each Guarantor and any other obligor upon the
Securities shall be deemed to have paid and discharged the entire Indebtedness
represented by the defeased Securities, which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 405 and the other Sections of
this Indenture referred to in (a) and (b) below, and to have satisfied all its
other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company and
upon Company Request, shall execute proper instruments acknowledging the same),
except for the following which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of

                                       56
<PAGE>
 
Holders of Defeased Securities to receive, solely from the trust fund described
in Section 404 and as more fully set forth in such Section, payments in respect
of the principal of, premium, if any, and interest on, such Securities, when
such payments are due, (b) the Company's obligations with respect to such
Defeased Securities under Sections 304, 305, 308, 1002 and 1003, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder, including,
without limitation, the Trustee's rights under Section 607, and (d) this Article
Four.  Subject to compliance with this Article Four, the Company may exercise
its option under this Section 402 notwithstanding the prior exercise of its
option under Section 403 with respect to the Securities.

     Section 403.  Covenant Defeasance.

     Upon the Company's exercise under Section 401 of the option applicable to
this Section 403, the Company and each Guarantor shall be released from its
obligations under any covenant contained in Sections 1005 through 1019(a),
inclusive, with respect to the Defeased Securities on and after the date the
conditions set forth in Section 404 are satisfied (hereinafter, "covenant
defeasance"), and the Defeased Securities shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "Outstanding" for all other purposes
hereunder.  For this purpose, such covenant defeasance means that, with respect
to the Defeased Securities, the Company and each Guarantor may omit to comply
with and shall have no liability in respect of any term, condition or limitation
set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 501(c), but, except as specified above, the remainder of this
Indenture and such Defeased Securities shall be unaffected thereby.

     Section 404.  Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 402
or Section 403 to the Defeased Securities:

     (1) The Company shall irrevocably have deposited or caused to be deposited
with the Trustee as trust funds in trust for the purpose of making the following
payments, specifically pledged as security for, and dedicated solely to, the
benefit of the Holders of such Securities, (a) United States dollars in an
amount, (b) U.S. Government Obligations which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms and
with no further reinvestment will provide, not later than one day before the due
date of any payment, money in an amount, or (c) a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants or a nationally recognized investment banking
firm expressed in a written certification thereof delivered to the Trustee, to
pay and discharge, and which shall be applied by the Trustee to pay and
discharge, the principal of, premium, if any, and interest on, the Defeased
Securities, on the Stated Maturity of such principal or interest (or on any date
after December 15, 2002 (such date being referred to as the "Defeasance
Redemption Date") if at or prior to electing to exercise either its option
applicable to Section 402 or its option applicable to Section 403, the Company
has delivered to the Trustee an irrevocable notice to redeem all of the
Outstanding Securities on the Defeasance Redemption Date);


     (2) In the case of an election under Section 402, the Company shall have
delivered to the Trustee an Opinion of Independent Counsel in the United States
stating that (A) the Company has received from, or there has been published by,
the Internal Revenue Service a ruling or (B) since the date hereof, there has
been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Independent Counsel in the United
States shall confirm that, the Holders of the Outstanding Securities will not
recognize income, gain or loss for federal income tax

                                       57
<PAGE>
 
purposes as a result of such defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have
been the case if such defeasance had not occurred;

     (3) In the case of an election under Section 403, the Company shall have
delivered to the Trustee an Opinion of Independent Counsel in the United States
to the effect that the Holders of the Outstanding Securities will not recognize
income, gain or loss for federal income tax purposes as a result of such
covenant defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such covenant defeasance had not occurred;

     (4) No Default or Event of Default shall have occurred and be continuing or
the date of such deposit or insofar as Section 501(h) or (i) is concerned, at
any time during the period ending on the 91st day after the date of deposit (it
being understood that this condition shall not be satisfied until the expiration
of such period);

     (5) Such defeasance or covenant defeasance shall not cause the Trustee for
the Securities to have a conflicting interest for purposes of the Trust
Indenture Act with respect to any other securities of the Company or any
Guarantor;

     (6) Such defeasance or covenant defeasance shall not result in a breach or
violation of, or constitute a Default under, this Indenture or any other
material agreement or instrument to which the Company, any Guarantor or any
Subsidiary is a party or by which it is bound;

     (7) Such defeasance or covenant defeasance shall not result in the trust
arising from such deposit constituting an investment company within the meaning
of the Investment Company Act of 1940, as amended, unless such trust shall be
registered under such Act or exempt from registration thereunder;

     (8) The Company shall have delivered to the Trustee an Opinion of
Independent Counsel to the effect that after the 91st day following the deposit,
the trust funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally;

     (9) The Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the holders of the Securities or any Guarantee over the other
creditors of the Company or any Guarantor with the intent of defeating,
hindering, delaying or defrauding creditors of the Company, any Guarantor or
others;

     (10) No event or condition shall exist that would prevent the Company from
making payments of the principal of, premium, if any, and interest on the
Securities on the date of such deposit or at any time ending on the 91st day
after the date of such deposit; and

     (11) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Independent Counsel, each stating that all
conditions precedent provided for relating to either the defeasance under
Section 402 or the covenant defeasance under Section 403 (as the case may be)
have been complied with.

     Opinions of Counsel or Opinions of Independent Counsel required to be
delivered under this Section shall be in form and substance reasonably
satisfactory to the Trustee and may have qualifications customary for opinions
of the type required and counsel delivering such opinions may rely on
certificates of the Company or government or other officials customary for
opinions of the type required, which certificates shall be limited as to matters
of fact, including that various financial covenants have been complied with.

Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all United
States dollars and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee pursuant to Section 404 in respect of the Defeased
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (excluding the Company or any of its
Affiliates acting as Paying Agent), as the Trustee may determine, to the Holders
of such Securities of all sums due and to become due thereon in respect of
principal, premium, if any, and interest, but such money need not be segregated
from other funds except to the extent required by law.  Money so held in trust
shall not be subject to the provisions of Article Thirteen.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
imposed, assessed or for the account of the Holders of the Defeased Securities.

     Anything in this Article Four to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
United States dollars or U.S. Government Obligations held by it as provided in
Section 404 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect defeasance or covenant defeasance.

     Section 406.  Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or U.S. Government Obligations in accordance with Section 402, 403 or 1201, as
the case may be by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Securities and any
Guarantor's obligations under this Indenture and any Guarantee shall be revived
and reinstated, with present and prospective effect, as though no deposit had
occurred pursuant to Section 402, 403 or 1201, as the case may be, until such
time as the Trustee or Paying Agent is permitted to apply all such United States
dollars or U.S. Government Obligations in accordance with Section 402, 403 or
1201, as the case may be; provided, however, that if the Company makes any
payment to the Trustee or Paying Agent of principal of, premium, if any, or
interest on any Security following the reinstatement of its obligations, the
Trustee or Paying Agent shall promptly pay any such amount to the Holders of the
Securities and the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the United States dollars and U.S.
Government Obligations held by the Trustee or Paying Agent.

     Section 502.  Acceleration of Maturity; Rescission and Annulment.

     (a) If an Event of Default (other than an Event of Default specified in
Sections 501(h) and (i)) shall occur and be continuing with respect to this
Indenture, the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities then outstanding may, and the Trustee at the
request of such Holders shall, declare all unpaid principal of, premium, if any,
and accrued interest on all Securities to be due and payable, by a notice in
writing to the Company (and to the Trustee if given by the Holders of the
Securities) and upon any such declaration, such principal, premium, if any, and
interest shall become due and payable immediately.  If an Event of Default
specified in clause (h) or (i) of Section 501 occurs with respect to the
Company, any Guarantor or any Significant Subsidiary and is continuing, then all
the Securities shall ipso facto become and be due and payable immediately in an
amount equal to the principal amount of the Securities, together with accrued
and unpaid interest, if any, to the date the Securities become due and payable,
without any declaration or other act on the part of the Trustee or any Holder.

     (b) Notwithstanding the foregoing provisions of Section 502(a), if a
declaration of acceleration in respect of the Securities because an Event of
Default specified in (i) clause (d) of Section 501(a) shall have occurred and be
continuing, such Event of Default and any consequential acceleration shall be
automatically rescinded if the Indebtedness that is the subject of such Event of
Default has been repaid, or if the default relating to such Indebtedness is
waived or cured and, if such Indebtedness has been accelerated, the holders
thereof have rescinded their declaration of acceleration in respect of such
Indebtedness (provided, in each case, that such repayment, waiver, cure or
rescission is effected within a period of 10 days from the continuation of such
default beyond the applicable grace period or the occurrence of such
acceleration), or (ii) clause (e) of Section 501(a) shall have occurred and be
continuing, such Event of Default and any consequential acceleration shall be
automatically rescinded if the proceedings or enforcement action with respect to
the Indebtedness that is the subject of such Event of Default is terminated or
rescinded, or such Indebtedness is repaid and only so long as any holder of such
Indebtedness shall not have applied any property or assets referenced in clause
(e) of Section 501(a) in satisfaction of such Indebtedness, and, in the case of
both clauses (i) and (ii) of this Section 502(b),

                                       61
<PAGE>
 
written notice of such repurchase, or cure or waiver and rescission, as the case
may be, shall have been given to the Trustee by the Company or by the requisite
holders of such Indebtedness or a trustee, fiduciary or agent for such holders,
within 45 days after such declaration of acceleration in respect of the
Securities and no other Event of Default shall have occurred which has not been
cured or waived during such 45-day period, and so long as such rescission of any
such acceleration does not conflict with any judgment or decree.

     (c) At any time after a declaration of acceleration with respect to the
Securities, but before a judgment or decree for payment of the money due has
been obtained by the Trustee, the Holders of a majority in aggregate principal
amount of the Securities Outstanding, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

     (1) the Company has paid or deposited with the Trustee a sum sufficient to
pay

          (i) all sums paid or advanced by the Trustee under this Indenture and
     the reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel,

          (ii) all overdue interest on all Outstanding Securities,

          (iii)  the principal of and premium, if any, on any Outstanding
     Securities which have become due otherwise than by such declaration of
     acceleration and interest thereon at a rate borne by the Securities, and

          (iv) to the extent that payment of such interest is lawful, interest
     upon overdue interest at the rate borne by the Securities which have become
     due otherwise than by such declaration of acceleration;

     (2) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction; and

     (3) all Events of Default, other than the non-payment of principal of,
premium, if any, and interest on the Securities that have become due solely by
such declaration of acceleration, have been cured or waived as provided in
Section 513.  No such rescission and annulment shall affect any subsequent
Default or impair any right consequent thereon.

     Section 503.  Other Remedies; Collection Suit by Trustee.

     (a) If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, or interest on the Securities or Guarantees or to
enforce the performance of any provision of the Securities or Guarantees or this
Indenture.

     (b) If an event of Default specified in clause (a) or (b) of Section 501
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company and/or any of the Guarantors
for the whole amount of principal of, premium, if any, and accrued interest
remaining unpaid, together with interest on overdue principal and, to the extent
that payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate per annum borne by the Securities and such
further amounts as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

     Section 504.  Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor, including any
Guarantor, upon the Securities or the property of the Company or of such other
obligor or their creditors, the Trustee (irrespective of whether the principal
of the Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand on the Company for the payment of overdue principal or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

     (a) to file and prove a claim for the whole amount of principal, and
premium, if any, and interest owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses disbursements and advances of the Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, if the Trustee shall consent to
the making of such payments directly to the Holders, to pay the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     Section 505.  Trustee May Enforce Claims without Possession of Securities.

     All rights of action and claims under this Indenture, the Securities or the
Guarantees may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name and as trustee of an express trust, and any recovery of judgment
shall, after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

     Section 506.  Application of Money Collected.

     Subject to Articles Thirteen and Fourteen of this Indenture, any money
collected by the Trustee pursuant to this Article or otherwise on behalf of the
Holders or the Trustee pursuant to this Article or through any proceeding or any

contemplated by this Article shall be applied, subject to applicable law, in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal, premium, if any, or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

     FIRST:  To the payment of all amounts due the Trustee under Section 607;

               respect of which or for the benefit of which such money has been
               collected, ratably, without preference or priority of any kind,
               according to the amounts due and payable on such Securities for
               principal, premium, if any, and interest; and

     THIRD:    The balance, if any, to the person or persons entitled thereto,
               including the Company, provided that all sums due and owing to
               the Holders and the Trustee have been paid in full as required by
               this Indenture.

     Section 507.  Limitation on Suits.

     (a) No Holder of any Securities shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture or the
Securities, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

     (b) such Holder has previously given written notice to the Trustee of a
continuing Event of Default;

     (c) the Holders of not less than 25% in principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as trustee
hereunder within 30 days after its receipt of such notice;

     (d) such Holder or Holders have offered to the Trustee reasonable security
or indemnity to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request;

     (e) the Trustee for 30 days after its receipt of such notice, request and

failed to institute any such proceeding; and

     (f) no direction inconsistent with such written request has been given to
the Trustee during such 30-day period by the Holders of a majority in principal
amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture, any Security or any Guarantee to affect, disturb or prejudice
the rights of any other Holders, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture,
any Security or any Guarantee, except in the manner provided in this Indenture
and for the equal and ratable benefit of all the Holders.


     (b) The foregoing provisions of Section 507(a) do not apply, however, to a
suit instituted by a Holder of a Security for the enforcement of the payment of
principal of, premiums, if any, or interest on, such Security on or after the
respective due dates expressed in such Security.

     Section 508.  Unconditional Right of Holders to Receive Principal, Premium
and Interest.

Stated Maturities expressed in such Security (or, in the case of redemption or
repurchase, on the Redemption Date or the repurchase date) and to institute suit
for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder; provided, however, that such

                                       64
<PAGE>
 
rights shall be subject to the subordination provisions contained in Articles
Thirteen and Fourteen of this Indenture.

     Section 509.  Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture or any Guarantee and such proceeding has

to the Trustee or to such Holder, then and in every such case the Company, any
Guarantor, any other obligor on the Securities, the Trustee and the Holders
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder, and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

     Section 510.  Rights and Remedies Cumulative.

     Except as otherwise provided in Section 308 with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law

     Section 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

     Section 512.  Control by Holders.

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Securities shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee under this Indenture,
provided that:

     (a) such direction shall not be in conflict with any rule of law or with
this Indenture (including, without limitation, Section 507) or any Guarantee,
expose the Trustee to personal liability, or be unduly prejudicial to Holders
not joining therein; and

     (b) subject to the provisions of Section 315 of the Trust Indenture Act,
the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     Section 513.  Waiver of Past Defaults.

the Outstanding Securities may on behalf of the Holders of all Outstanding
Securities waive any past Default hereunder and its consequences, except a

Security; or

                                       65
<PAGE>
 
     (b) in respect of a covenant or a provision hereof which under this
Indenture cannot be modified or amended without the consent of the Holder of
each Security Outstanding affected by such modification or amendment.

     Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

     Section 514.  Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant, but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of, premium, if any, or
interest on, any Security on or after the respective Stated Maturities expressed
in such Security (or, in the case of redemption, on or after the Redemption
Date).

     Section 515.  Remedies Subject to Applicable Law.

     All rights, remedies and powers provided by this Article Five may be
exercised only to the extent that the exercise thereof does not violate any
applicable provision of law in the premises, and all the provisions of this
Indenture are intended to be subject to all applicable mandatory provisions of
law which may be controlling in the premises and to be limited to the extent
necessary so that they will not render this Indenture invalid, unenforceable or
not entitled to be recorded, registered or filed under the provisions of any
applicable law.


                                  ARTICLE SIX

                                  THE TRUSTEE

     Section 601.  Duties of Trustee.

     Subject to the provisions of Trust Indenture Act Sections 315(a) through
315(d):

     (a) if a Default or an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in its exercise thereof as a

<PAGE>
 
          (2) in the absence of bad faith or willful misconduct on its part, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture.  However, the Trustee shall examine the certificates and
     opinions to determine whether or not they conform to the requirements of
     this Indenture;

     (c) the Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except

     this Section 601;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it is proved that the Trustee

     takes or omits to take in good faith, in accordance with a direction of the
     Holders of a majority in principal amount of Outstanding Securities
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee, or exercising any trust or power confirmed
     upon the Trustee under this Indenture;

     (d) no provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder or in the exercise of any of its rights or powers
if it shall have reasonable grounds for believing that repayment of such funds
or adequate security or indemnity against such risk or liability is not
reasonably assured to it;

     (e) whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to Subsections (a),
(b), (c) and (d) of this Section 601; and

     (f) the Trustee shall not be liable for interest on any money or assets
received by it except as the Trustee may agree with the Company.  Assets held in
trust by the Trustee need not be segregated from other assets except to the
extent required by law.

     Section 602.  Notice of Defaults.

     Within 90 days after a Responsible Officer of the Trustee receives notice
of the occurrence of any Default or Event of Default, the Trustee shall transmit
by mail to all Holders and any other persons entitled to receive reports
pursuant to Section 313(c) of the Trust Indenture Act as their names and
addresses appear in the Security Register, notice of such Default or Event of
Default hereunder known to the Trustee, unless such Default or Event of Default
shall have been cured or waived; provided however, that, except in the case of a
Default or an Event of Default in the payment of the principal of, premium, if
any, or interest on any Security, the Trustee shall be protected in withholding
such notice if and so long as a trust committee of Responsible Officers of the

or matters stated in any resolution, certificate statement, instrument, opinion,
report, notice, request, direction, consent, order, approval, appraisal, bond,
debenture, note, coupon, security or other paper or document unless requested in
writing to do so by the Holders of not less than a majority in aggregate
principal amount of the Securities then Outstanding; provided that, if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable security or indemnity against such expenses or liabilities as a
condition to proceeding; the reasonable expenses of every such investigation so
requested by the Holders of not less than a majority in aggregate principal
amount of the Securities Outstanding shall be paid by the Company or, if paid by
the Trustee or any predecessor Trustee, shall be repaid by the Company upon
demand; provided, further, the Trustee in its discretion may make such further

an Officers' Certificate; and

     (h) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible

                                       68
<PAGE>
 
for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder.

     Section 604.  Trustee Not Responsible for Recitals, Dispositions of
Securities or Application of Proceeds Thereof.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness.  Neither the
Trustee nor any Authenticating Agent makes any representations as to the
validity or sufficiency of this Indenture or of the Securities, except that the
Trustee represents that it is duly authorized to execute and deliver this
Indenture, authenticate the Securities and perform its obligations hereunder and
that the statements made by it in any Statement of Eligibility and Qualification
on Form T-1 supplied to the Company are or will be true and accurate subject to
the qualifications set forth therein.  The Trustee shall not be accountable for
the use or application by the Company of Securities or the proceeds thereof nor
shall the Trustee be responsible for any statement in any registration statement
for the Securities under the Securities Act or responsible for the determination
as to which beneficial owners are entitled to receive notices hereunder.

     Section 605.  Trustee and Agents May Hold Securities; Collections; etc.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, or any Guarantor in its individual
or any other capacity, may become the owner or pledgee of Securities, with the
same rights it would have if it were not the Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent and, subject to Sections
608 and 613 hereof and Trust Indenture Act Sections 310 and 311, may otherwise
deal with the Company or any Guarantor and receive, collect, hold and retain
collections from the Company or any Guarantor with the same rights it would have
if it were not the Trustee, Paying Agent, Security Registrar or such other
agent.

     Section 606.  Money Held in Trust.

     All moneys received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received, but
need not be segregated from other funds except to the extent required by
mandatory provisions of law.  Except for funds or securities deposited with the
Trustee pursuant to Articles Four, Eleven and Twelve and Sections 1011 and 1012,
the Trustee shall be required to invest all moneys received by the Trustee,
until used or applied as herein provided, in Cash Equivalents in accordance with
the written directions of the Company.

     Section 607.  Compensation and Indemnification of Trustee and Its Prior
Claim.

     The Company covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation for all services
rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
and, except as otherwise expressly provided herein, the Company covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made
by or on behalf of the Trustee in accordance with any of the provisions of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ) except any such expense, disbursement or advance as may arise
from its negligence, bad faith or willful misconduct.  The Company also
covenants and agrees to indemnify the Trustee and each predecessor Trustee for,
and to hold it harmless against, any claim, loss, liability, tax, assessment or
other governmental charge (other than taxes applicable to the Trustee's
compensation hereunder) or expense incurred without negligence, bad faith or
willful misconduct on its part arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder including enforcement

                                       69
<PAGE>
 
of this Section 607 and also including any liability which the Trustee may incur
as a result of the failure to withhold, pay or report any tax, assessment or
other governmental charge, and the costs and expenses of defending itself
against or investigating any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.  The obligations of the
Company under this Section 607 to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for reasonable expenses, disbursements and advances shall constitute an
additional obligation hereunder and shall survive the satisfaction and discharge
of this Indenture and the resignation or removal of the Trustee and each
predecessor Trustee.  The Company shall have the right to defend any claim or
threatened claim asserted against an indemnitee for which it may seek indemnity,
and the indemnitee shall cooperate in the defense unless, in the reasonable
opinion of the indemnitee's counsel, the indemnitee has an interest materially
adverse to the Company or any Guarantor or a potential conflict of interest
exists between the indemnitee and the Company or any Guarantor, in which case
the indemnitee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel; provided that the Company shall
only be responsible for the reasonable fees and expenses of one law firm (in
addition to local counsel, to the extent such local counsel is reasonably
required) arising out of the same general allegations or circumstances, such law
firm to be designated by the indemnitee and reasonably acceptable to the
Company.

     Section 608.  Conflicting Interests.

     The Trustee shall comply with the provisions of Section 310(b) of the Trust
Indenture Act.

     Section 609.  Trustee Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to
act as trustee under Trust Indenture Act Section 310(a)(5) and which shall have
a combined capital and surplus of at least $100,000,000, to the extent there is
an institution eligible and willing to serve.  If the Trustee does not have an
office in The City of New York, the Trustee may appoint an agent in The City of
New York reasonably acceptable to the Company to conduct any activities which
the Trustee may be required under this Indenture to conduct in The City of New
York.  If such Trustee publishes reports of condition at least annually,
pursuant to law or to the requirements of federal, state, territorial or
District of Columbia supervising or examining authority, then for the purposes
of this Section 609, the combined capital and surplus of such corporation shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 609, the Trustee
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

     Section 610.  Resignation and Removal; Appointment of Successor Trustee.

     (a) No resignation or removal of the Trustee and no appointment of a
successor trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor trustee under Section 611.

     (b) The Trustee, or any trustee or trustees hereafter appointed, may at any
time resign by giving written notice thereof to the Company.  Upon receiving
such notice or resignation, the Company shall promptly appoint a successor
trustee, and a copy of such appointment shall be delivered to the resigning
Trustee and to the successor trustee.  If an instrument of acceptance by a
successor trustee shall not have been delivered to the Trustee within 30 days
after the giving of such notice of resignation, the resigning Trustee may, or
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor trustee.  Such
court may thereupon, after such notice, if any, as it may deem proper, appoint
and prescribe a successor trustee.

                                       70
<PAGE>
 
     (c) The Trustee may be removed at any time for any cause or for no cause by
an Act of the Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities, delivered to the Trustee and to the Company.

     (d)  If at any time:

          (1) the Trustee shall fail to comply with the provisions of Trust
     Indenture Act Section 310(b) after written request therefor by the Company
     or by any Holder who has been a bona fide Holder of a Security for at least
     six months,

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Security for at least six
     months, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent, or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then in any such case, (i) the Company may remove the Trustee, or (ii) subject
to Section 514, the Holder of any Security who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor trustee and shall comply with the applicable
requirements of Section 611.  If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy the Company has not
appointed a successor Trustee, a successor trustee shall be appointed by the Act
of the Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee.  Such successor trustee so
appointed shall forthwith upon its acceptance of such appointment become the
successor trustee and supersede the successor trustee appointed by the Company.
If no successor trustee shall have been so appointed by the Company or the
Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Holder of any Security who has been a bona fide Holder for at
least six months may, subject to Section 514, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor trustee.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor trustee by mailing written
notice of such event by first-class mail, postage prepaid, to the Holders of
Securities as their names and addresses appear in the Security Register.  Each
notice shall include the name of the successor trustee and the address of its
Corporate Trust Office or agent hereunder.

     Section 611.  Acceptance of Appointment by Successor.

     Every successor trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee as if originally named as Trustee hereunder; but,
nevertheless, on the written request of the Company or the successor trustee,
upon payment of its charges pursuant to Section 607 then unpaid, such retiring
Trustee shall pay over to the successor trustee all moneys at the time held by

                                       71
<PAGE>
 
it hereunder and shall execute and deliver an instrument transferring to such
successor trustee all such rights, powers, duties and obligations.  Upon request
of any such successor trustee, the Company shall execute any and all instruments
for fully and certainly vesting in and confirming to such successor trustee all
such rights and powers.

     No successor trustee with respect to the Securities shall accept
appointment as provided in this Section 611 unless at the time of such
acceptance such successor trustee shall be eligible to act as trustee under the
provisions of Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $100,000,000 and have a
Corporate Trust Office or an agent selected in accordance with Section 609.

     Upon acceptance of appointment by any successor trustee as provided in this
Section 611, the Company shall give notice thereof to the Holders of the
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the Security Register.  If the acceptance of appointment is
substantially contemporaneous with the appointment, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
610.  If the Company fails to give such notice within 10 days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Company.

     Section 612.  Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee (including the trust created by this Indenture) shall be
the successor of the Trustee hereunder, provided that such corporation shall be
eligible under Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $100,000,000 and have a
Corporate Trust Office or an agent selected in accordance with Section 609,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.

     If at the time such successor to the Trustee shall succeed to the trusts
created by this Indenture any of the Securities shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor Trustee and deliver such Securities so
authenticated; and, if at that time any of the Securities shall not have been
authenticated, any successor to the Trustee may authenticate such Securities
either in the name of any predecessor hereunder or in the name of the successor
trustee; and in all such cases such certificate shall have the full force which
it is anywhere in the Securities or in this Indenture provided that the
certificate of the Trustee shall have; provided that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

     Section 613.  Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
other obligor under the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).  A Trustee who has resigned or been
removed shall be subject to Trust Indenture Act Section 311(a) to the extent
indicated therein.

     Section 614.  Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents acceptable to and
at the expense of the Company which shall be authorized to act on behalf of the
Trustee to authenticate Securities issued upon original issue and upon exchange,
registration of transfer, partial conversion or partial redemption

                                       72
<PAGE>
 
or pursuant to Section 308, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a person organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $100,000,000 and
subject to supervision or examination by federal or state authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any person into which an Authenticating Agent may be merged or converted or
with which it may be consolidated, or any person resulting from any merger,
conversion or consolidation to which such Authenticating Agent shall be a party,
or any person succeeding to the corporate agency or corporate trust business of
an Authenticating Agent, shall continue to be an Authenticating Agent, provided
such person shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Company or the Trustee may at
any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent and to the Company or the Trustee,
as the case may be.  Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail notice of such appointment by first-class mail, postage
prepaid, to all Holders as their names and addresses appear in the Security
Register.  Any successor Authenticating Agent upon acceptance of its appointment
under this Section shall become vested with all the rights, powers and duties of
its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible to act as such under the provisions of this Section.

     Any Authenticating Agent by the acceptance of its appointment shall be
deemed to have represented to the Trustee that it is eligible for appointment as
Authenticating Agent under this Section and to have agreed with the Trustee
that: it will perform and carry out the duties of an Authenticating Agent as
herein set forth, including among other things the duties to authenticate
Securities when presented to it in connection with the original issuance and
with exchanges, registrations of transfer or redemptions or conversions thereof
or pursuant to Section 306; it will keep and maintain, and furnish to the
Trustee from time to time as requested by the Trustee, appropriate records of
all transactions carried out by it as Authenticating Agent and will furnish the
Trustee such other information and reports as the Trustee may reasonably
require; and it will notify the Trustee promptly if it shall cease to be
eligible to act as Authenticating Agent in accordance with the provisions of
this Section.  Any Authenticating Agent by the acceptance of its appointment
shall be deemed to have agreed with the Trustee to indemnify the Trustee against
any loss, liability or expense incurred by the Trustee and to defend any claim
asserted against the Trustee by reason of any acts or failures to act of such
Authenticating Agent, but such Authenticating Agent shall have no liability for
any action taken by it in accordance with the specific written direction of the
Trustee.

                                       73
<PAGE>
 
     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

     If an appointment is made pursuant to this Section, the Securities may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

     This is one of the Securities described in the within-mentioned Indenture.

other Holders with respect to their rights under this Indenture or the

shall have the protection of Trust Indenture Act Section 312(c).  Further, every
Holder of Securities, by receiving and holding the same, agrees with the Company
and the Trustee that neither the Company nor the Trustee or any agent of either
of them shall be held accountable by reason of the disclosure of any information
as to the names and addresses of the Holders in accordance with Trust Indenture
Act Section 312, regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Trust Indenture Act Section 312.

     Section 703.  Reports by Trustee.

sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all of its properties and assets as an entirety to any person or
persons, or permit any of its Restricted Subsidiaries to enter into any such
transaction or series of related transactions if such transaction or series of
related transactions, in the aggregate, would result in a sale, assignment,
conveyance, transfer, lease or disposition of all or substantially all of the
properties and assets of the Company or of the Company and its Restricted
Subsidiaries, taken as a whole, to any other person or persons, unless at the

          (i) either (A)(1) if the transaction or transactions is a merger or
     consolidation involving the Company as a constituent to the merger or
     consolidation, the Company shall be the surviving person of such merger or
     consolidation or (2) if the transaction or related transactions is a merger

     merger or consolidation, such Restricted Subsidiary shall be the surviving
     person of such merger or consolidation and such surviving person shall be a
     Restricted Subsidiary, or (B)(1) the person formed by such consolidation or
     into which the Company or such Restricted Subsidiary is merged or to which
     the properties and assets of the Company or such Restricted Subsidiary, as
     the case may be, substantially as an entirety, are transferred (any such
     surviving person or transferee person being the "Surviving Entity") shall
     be a corporation organized and existing under the laws of the United States
     of America, any State thereof or the District of Columbia and (2) in the
     case of a transaction involving the Company as a constituent to the merger
     or consolidation, or as the transferor of all or substantially all of its
     assets or taken as a whole, all or substantially all of the assets of it
     and the Restricted Subsidiaries, the Surviving Entity shall expressly
     assume by a supplemental indenture executed and delivered to the Trustee,
     in form satisfactory to the Trustee, all the obligations of the Company
     under the Securities and the Indenture, and in each case, the Indenture
     shall remain in full force and effect;

          (ii) immediately after giving effect to such transaction or
     transactions on a pro forma basis (including any Indebtedness incurred or
     anticipated to be incurred in connection with or as a result of such
     transaction or series of related transactions), no Default or Event of
     Default will have occurred and be continuing;

          (iii)  immediately after giving effect to such transaction or

     statements are available ending immediately prior to the consummation of
     such transaction with the appropriate adjustments with respect to the
     transaction being included in such proforma calculation), the Company (or

     1008(a);

          (iv) at the time of the transaction, each Guarantor, if any, unless it
     is the other party to the transactions described above, will have by
     supplemental indenture confirmed that its Guarantees shall apply to such
     person's obligations hereunder and under the Securities;

          (v) at the time of the transaction if any of the property or assets of
     the Company or any of its Restricted Subsidiaries would thereupon become
     subject to any Lien, the provisions of Section 1010 are complied with; and

                                       76
<PAGE>
 
          (vi) at the time of the transaction the Company or the Surviving
     Entity will have delivered, or caused to be delivered, to the Trustee, in
     form and substance reasonably satisfactory to the Trustee, an Officers'
     Certificate and an Opinion of Counsel, each to the effect that such
     consolidation merger, transfer, sale, assignment, conveyance, transfer,
     lease or other transaction and the supplemental indenture in respect
     thereof comply with this Indenture and that all conditions precedent herein
     provided for relating to such transaction have been complied with.

     (b) Each Guarantor shall not, and the Company will not permit a Guarantor
to, in a single transaction or through a series of related transactions,
consolidate with or merge with or into any other person (other than the Company
or any other Guarantor) or sell, assign, convey, transfer, lease or otherwise
dispose of all or substantially all of its properties and assets as an entirety
to any person or persons (other than the Company or any other Guarantor), unless
at the time and after giving effect thereto:

          (i) either (1) the Guarantor will be the continuing corporation or (2)
     the person (if other than the Guarantor) formed by such consolidation or
     into which such Guarantor is merged or the person which acquires by sale,

     all of the properties and assets of the Guarantor (the "Surviving Guarantor
     Entity") will be a corporation duly organized and validly existing under
     the laws of the United States of America, any state thereof or the District
     of Columbia and such person expressly assumes, by a supplemental indenture,
     in a form satisfactory to the Trustee, all the obligations of such
     Guarantor under its Guarantee of the Securities and this Indenture, and
     such Guarantee will remain in full force and effect;

          (ii) immediately before and immediately after giving effect to such
     transaction or transactions, on a pro forma basis, no Default or Event of
     Default shall have occurred and be continuing; and

          (iii)  at the time of the transaction such Guarantor or the Surviving
     Guarantor Entity will have delivered, or caused to be delivered, to the
     Trustee, in form and substance reasonably satisfactory to the Trustee, an
     Officers' Certificate and an Opinion of Counsel, each to the effect that
     such consolidation, merger, transfer, sale, assignment, conveyance, lease
     or other transaction and the supplemental indenture in respect thereof
     comply with this Indenture and that all conditions precedent therein
     provided for relating to such transaction have been complied with.

     Notwithstanding the foregoing provisions of this Section 801(b), Section
801(b) shall not apply upon any sale, exchange or transfer of all of the
Company's Capital Stock in, or all or substantially all of the assets of, a
Guarantor that shall be released in accordance with Section 1018(d).

     Section 802.  Successor Substituted.

     Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or disposition of all or substantially all of the properties and
assets of the Company or any Guarantor, if any, in accordance with Section 801,
in which the Company or such Guarantor, as the case may be, is not the Surviving
Entity or the Surviving Guarantor Entity, as the case may be, then (i) the
Surviving Entity or the Surviving Guarantor Entity, as the case may be, shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company or such Guarantor, as the case may be, under this Indenture, in the
Securities and/or the Guarantee, as the case may be, with the same effect as if
such Surviving Entity or Surviving Guarantor Entity had been named as the
Company or such Guarantor, as the case may be, herein, in the Securities and/or
in the Guarantee, as the case may be, and (ii) when such successor assumes all
the obligations of its predecessor under and in accordance with this Indenture,
the Securities or a Guarantee, as the case may be, the predecessor shall be
released from those obligations and covenants hereof and the Securities or the
Guarantees, as the case may be, provided that in the case

                                       77
<PAGE>
 
of a transfer by lease by the Company or any Guarantor of all or substantially
all of its assets, the predecessor shall not be released from the payment of
principal and interest on the Securities or a Guarantee, as the case may be;
provided further that, solely for purposes of computing cumulative Consolidated
Net Income for purposes of clause (b) of Section 1009(a), the cumulative
Consolidated Net Income of any persons other than the Company and the Restricted
Subsidiaries shall only be included for periods subsequent to the effective time
of such merger, consolidation, combination or transfer of assets.

     For all purposes of this Indenture and the Securities (including the
provision of this Section 802 and Sections 1008, 1009 and 1010), Subsidiaries of
any Surviving Entity will, upon such transaction or series of transactions,
become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant
to Section 1017, and all Indebtedness, and all Liens on property or assets, of
the Company and the Restricted Subsidiaries immediately prior to such
transaction or series of transactions will be deemed to have been incurred upon
such transaction or series of transactions.

     In executing, or accepting the additional trusts created by, any
supplemental indenture, agreement, instrument or waiver permitted by this

     Section 908.  Revocation and Effects of Consents.

     Until an amendment or waiver becomes effective, a consent to it by a Holder
of a Security is a continuing consent by the Holder and every subsequent Holder
of a Security or portion of a Security that evidences the same Indebtedness as
the consenting Holder's Security, even if a notation of the consent is not made
on any Security.  However, any such Holder, or subsequent Holder, may revoke the
consent as to his Security or portion of a Security if the Trustee receives the
notice of revocation before the date the amendment or waiver becomes effective.
An amendment or waiver shall become effective in accordance with its terms and
thereafter bind every Holder.

have consented in writing to such supplemental indenture.

     Section 1001.  Payment of Principal, Premium and Interest.

     The Company shall duly and punctually pay the principal of, premium, if
any, and interest on the Securities in accordance with the terms of the
Securities and this Indenture.

served.  Initially, such office or agency will be State Street Bank & Trust
Company of New York, N.A., 61 Broadway, 15th Floor, New York, New York 10006,
and the Company will give prompt written notice to the Trustee of any change in
the location of any such offices or agencies.  If at any time the Company shall
fail to maintain any such required offices or agencies or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the office of the agent of the Trustee, and
the Company hereby appoints the Trustee such agent as its agent to receive all
such presentations surrenders, notices and demands.

     The Company may from time to time designate one or more other offices or
agencies (in or outside of The City of New York) where the Securities may be
presented or surrendered for any or all such purposes, and may from time to time
rescind such designation.  The Company will give prompt written notice to the
Trustee of any such designation or rescission and any change in the location of
any such office or agency.

     The Trustee shall initially act as Paying Agent for the Securities.

     Section 1003.  Money for Security Payments to Be Held in Trust.

     If the Company or any of its Affiliates shall at any time act as Paying
Agent it will on or before each due date of the principal of, premium if any, or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Holders entitled thereto a sum sufficient to pay the principal, premium
if

                                       81
<PAGE>
 
any, or interest so becoming due until such sums shall be paid to such Holders
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

     If the Company or any of its Affiliates is not acting as Paying Agent, the
Company will, on or before each due date of the principal of, premium, if any,
or interest on any of the Securities, deposit with a Paying Agent a sum in same
day funds sufficient to pay the principal, premium, if any, or interest so
becoming due, such sum to be held in trust for the benefit of the persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of such action or
any failure so to act.

     If the Company is not acting as Paying Agent, the Company will cause each
Paying Agent other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such, Paying Agent will:

     (a) hold all sums held by it for the payment of the principal of, premium
if any, or interest on the Securities in trust for the benefit of the persons
entitled thereto until such sums shall be paid to such persons or otherwise
disposed of as herein provided:

     (c) at any time during the continuance of any such Default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d) acknowledge, accept and agree to comply in all aspects with the
provisions of this Indenture relating to the duties, rights and disabilities of
such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or
interest on any Security and remaining unclaimed for two years after such
principal and premium, if any, or interest has become due and payable shall
promptly be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in the New York Times and The
Wall Street Journal (national edition), and mail to each such Holder, notice

     Section 1004.  Corporate Existence.

     Subject to Article Eight, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect the corporate
existence and related rights and franchises (charter and statutory) of the
Company and each Restricted Subsidiary; provided, however, that the Company
shall not be required to preserve any such right or franchise or the corporate
existence of any such Restricted Subsidiary if the Board of Directors of the
Company shall determine that the preservation thereof is no longer necessary or
desirable in the conduct of the business of the Company and its Restricted
Subsidiaries as a whole and that the loss thereof would not reasonably be
expected to have a material adverse effect on the ability of the Company to
perform its obligations hereunder; and provided, further,  however, that the
foregoing shall not prohibit a sale, transfer or conveyance of a Restricted
Subsidiary or any of its assets in compliance with the terms of this Indenture.

     Section 1005.  Payment of Taxes and Other Claims.

     The Company shall pay or discharge or cause to be paid or discharged, on or
before the date the same shall become due and payable, (a) all taxes,
assessments and governmental charges levied or imposed upon the Company or any
of its Restricted Subsidiaries shown to be due on any return of the Company or
any of its Restricted Subsidiaries or otherwise assessed or upon the income,
profits or property of the Company or any of its Restricted Subsidiaries if
failure to pay or discharge the same could reasonably be expected to have a
material adverse effect on the ability of the Company or any Guarantor to
perform any of their obligations hereunder and (b) all lawful claims for labor,
materials and supplies, which, if unpaid, would by law become a Lien upon the
property of the Company or any of its Restricted Subsidiaries, except for any
Lien permitted to be incurred under Section 1010, if failure to pay or discharge
the same could reasonably be expected to have a material adverse effect on the
ability of the Company or any Guarantor to perform any of their obligations
hereunder; provided however, that the Company and the Guarantors shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings properly instituted and
diligently conducted and in respect of which appropriate reserves (in the good
faith judgment of management of the Company) are being maintained in accordance
with GAAP.

     Section 1006.  Maintenance of Properties.

     The Company shall cause all material properties owned by the Company and
any of its Restricted Subsidiaries or used or held for use in the conduct of its
business or the business of any of its Restricted Subsidiaries to be maintained
and kept in good condition, repair and working order (ordinary wear and tear
excepted) and supplied with all necessary equipment and will cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the reasonable judgment of the Company may be consistent with
sound business practice and necessary so that the business carried on in
connection therewith may be properly conducted at all times; provided, however,
that nothing in this Section shall prevent the Company from discontinuing the
maintenance of any of such properties if such discontinuance is, in the
reasonable judgment of the Company, desirable in the conduct of its business or
the business of any of its Restricted Subsidiaries and not reasonably expected
to have a material adverse effect on the ability of the Company to perform its
obligations hereunder.

     Section 1007.  Insurance.

     The Company shall at all times keep all of its and its Restricted
Subsidiaries' properties which are of an insurable nature insured with insurers,
believed by the Company in good faith to be financially sound and responsible,
against loss or damage to the extent that property of similar character is
usually so insured by corporations similarly situated and owning like properties
engaged in similar operations in the same general geographic areas in which the
Company and its Restricted Subsidiaries operate, except

                                       83
<PAGE>
 
where the failure to do so could not reasonably be expected to have a material
adverse effect on the condition (financial or otherwise), earnings, business
affairs or prospects of the Company and its Restricted Subsidiaries, taken as a
whole, provided that such insurance is generally available at commercially
reasonable rates, and further provided that the Company may self-insure, or
insure through captive insurers or insurance cooperatives to the extent
consistent with prudent business practices.  Such insurance shall be in such
amounts, contain such terms, be in such forms and be for such periods as are
customary in the Company's industry and commercially reasonable.  Such insurance
may be subject to such deductibles as are customary in the industry.

     Section 1008.  Limitation on Indebtedness.

     (a) The Company will not, and will not permit any of the Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or in any other manner become liable, contingently or otherwise (in each case,
to "incur"), for the payment of any Indebtedness (including any Acquired
Indebtedness); provided that (i) the Company and each Guarantor will be
permitted to incur Indebtedness (including Acquired Indebtedness) and (ii) a
Restricted Subsidiary which is not a Guarantor will be permitted to incur
Acquired Indebtedness if (y), immediately after giving pro forma effect thereto,
the Consolidated Fixed Charge Coverage Ratio of the Company would be equal to or
greater than 2.00:1 and (z) no Default or Event of Default shall have occurred
and be continuing at the time such Indebtedness or Acquired Indebtedness, as the
case may be, is incurred or would occur as a result of such incurrence.

     (b) Notwithstanding the foregoing, the Company (and, to the extent
specifically set forth below, the Guarantors) may incur each and all of the
following Indebtedness (including any Acquired Indebtedness):

          (i) (a) Indebtedness of the Company or any Guarantor under the Credit
     Facility in an aggregate principal amount at any time outstanding not to
     exceed $100,000,000 and any fees, premiums, expenses (including costs of
     collection), indemnities and other similar amounts payable in connection
     with such Indebtedness; and (b) other Indebtedness of the Company or any
     Guarantor outstanding on the Issue Date (other than Indebtedness described
     in clause (i)(a), (ii) or (v) of this Section 1008(b)) and listed in
     Schedule 1008 hereto;

          (ii) Indebtedness of the Company evidenced by the Securities and
     Indebtedness of each Guarantor under its Guarantee;

          (iii)  Interest Rate Protection Obligations of the Company or any
     Guarantor covering Indebtedness of the Company or any Guarantor incurred in
     the ordinary course of business and permitted to be incurred by the Company
     or any Guarantor, as the case may be, pursuant to this Indenture; provided
     that the notional principal amount of any such Interest Rate Protection
     Obligations does not exceed 100% of the principal amount of the
     Indebtedness to which such Interest Rate Protection Obligations expressly
     relates;

          (iv) Indebtedness of the Company or any of the Guarantors under
     Currency Agreement Obligations; provided that such Currency Agreement
     Obligations (a) do not increase the Indebtedness or other obligations of
     the Company and the Guarantors outstanding other than as a result of
     fluctuations in foreign currency exchange rates or by reason of fees,
     indemnities and compensation payable thereunder and (b) are entered into in
     the ordinary course of business for the purpose of limiting risks that
     arise in the ordinary course of business of the Company and the Guarantors;

          (v) Indebtedness of the Company owed to a Restricted Subsidiary and
     Indebtedness of a Guarantor owed to the Company or another Guarantor;
     provided that (a) any subsequent issuance or transfer of Capital Stock or
     any Designation that results in such Restricted Subsidiary

                                       84
<PAGE>
 
     or Guarantor (as the case may be) ceasing to be a Restricted Subsidiary or
     any subsequent transfer, pledge or assignment of such Indebtedness (other
     than to the Company or another Guarantor) will be deemed to constitute the
     incurrence of such Indebtedness by the Company or such Guarantor, as the
     case may be, not permitted by this clause (v) and (b) any such Indebtedness
     of the Company owed to a Restricted Subsidiary and any such Indebtedness of
     a Guarantor owed to another Guarantor, must be unsecured and subordinated
     in right of payment to the prior payment in full and performance of the
     Company's obligations under this Indenture and the Securities, and such
     Guarantor's obligations under its Guarantee, as the case may be;

          (vi) Indebtedness of the Company or any Guarantor incurred in respect
     of bid, performance and payment bonds (other than in respect of
     Indebtedness), surety bonds, trade letters of credit, bankers' acceptances
     and letters of credit supporting bids, advance payments and performance
     obligations of the Company or any Guarantor (other than in respect of
     Indebtedness), in each case incurred in the ordinary course of business;

          (vii)  Indebtedness of the Company or any Guarantor (a) representing
     Capitalized Lease Obligations or (b) Purchase Money Obligations for
     property acquired in the ordinary course of business, which taken together
     do not exceed $20,000,000 in aggregate amount at any time outstanding;

          (viii)  Indebtedness of the Company or any Guarantor to the extent the
     proceeds thereof are used to Refinance Indebtedness of the Company
     (including all or a portion of the Securities) or any Guarantor to the
     extent the Indebtedness to be Refinanced, has been incurred under or
     referred to in Section 1008(a) or clauses (i)(b), (ii), (vii)(b) or (ix) of
     this Section 1008(b); provided that the principal amount of Indebtedness
     incurred pursuant to this clause (viii) (or, if such Indebtedness provides
     for an amount less than the principal amount thereof to be due and payable
     upon a declaration of acceleration of the maturity thereof, the original
     issue price of such Indebtedness) shall not exceed the sum of the principal
     amount of Indebtedness so Refinanced (or, if such Indebtedness provides for
     an amount less than the principal amount thereof to be due and payable upon
     a declaration of acceleration of the maturity thereof, the original issue
     price of such Indebtedness plus any accredited value attributable thereto
     since the original issuance of such Indebtedness) plus the amount of any
     premium required to be paid in connection therewith pursuant to the terms
     of such Indebtedness or the amount of any premium reasonably determined by
     the Company or a Guarantor, as applicable, as necessary to accomplish the
     foregoing by means of a tender or exchange offer or privately negotiated
     purchase, plus the amount of expenses in connection therewith; and

          (ix) Indebtedness of the Company and the Guarantors (which may include
     any Indebtedness incurred for any purpose, including but not limited to the
     purposes referred to in clauses (i) through (viii) of this Section 1008(b))
     in an aggregate amount which, together with the amount of all other
     Indebtedness of the Company and the Guarantors outstanding on the date of
     such incurrence (other than Indebtedness permitted by clauses (i) through
     (viii) of this Section 1008(b) or Section 1008(a)) does not exceed
     $25,000,000.

     (c) Notwithstanding Section 1008(b), neither the Company nor any Guarantor
shall incur any Indebtedness pursuant to Section 1008(b) if the proceeds thereof
are used, directly or indirectly, (i) to Refinance any Subordinated Obligations
of the Company or such Guarantor, as the case may be, unless such Indebtedness
(A) shall be subordinated to the Securities or the relevant Guarantee to at
least the same extent as such Subordinated Obligations, (B) has an Average Life
to Stated Maturity greater than the lesser of (y) the remaining Average Life to
Stated Maturity of the Subordinated Obligations being Refinanced or (z) the
remaining Average Life to Stated Maturity of the Securities, and (C) has a
Stated Maturity for its final scheduled principal payment later than the Stated
Maturity for the final scheduled principal payment of the Subordinated
Obligations being Refinanced, or (ii) to Refinance any Pari Passu

                                       85
<PAGE>
 
Indebtedness, unless such Refinancing does not reduce the Average Life to Stated
Maturity or the Stated Maturity of such Pari Passu Indebtedness.

     Section 1009.  Limitation on Restricted Payments.

     (a) The Company will not, and will not permit any of the Restricted
Subsidiaries to, directly or indirectly:

          (i) declare or pay any dividend or make any other distribution or
     payment on or in respect of Capital Stock of the Company or any Restricted
     Subsidiary or any payment made to the direct or indirect holders (in their
     capacities as such) of Capital Stock of the Company or any Restricted
     Subsidiary (other than dividends or distributions payable solely (a) in
     Capital Stock of the Company (other than Redeemable Capital Stock), (b) in
     rights to purchase Capital Stock of the Company (other than Redeemable
     Capital Stock) and (c) to the Company);

          (ii) purchase, redeem, defease or otherwise acquire or retire for
     value any Capital Stock of the Company or any Restricted Subsidiary (other
     than any such Capital Stock owned by a Wholly-Owned Restricted Subsidiary);

          (iii)  make any principal payment on, or purchase, defease,
     repurchase, redeem or otherwise acquire or retire for value, prior to any
     scheduled maturity, scheduled repayment, scheduled sinking fund payment or
     other Stated Maturity, any Subordinated Obligations (other than any such
     Subordinated Obligations owed to a Wholly-Owned Restricted Subsidiary); or

          (iv) make any Investment (other than a Permitted Investment) in any
     person

     (such payments or Investments described in (but not excluded from) the
     preceding clauses (i) (other than by reason of the proviso thereto), (ii),
     (iii) and (iv) are collectively referred to as "Restricted Payments"),
     unless, at the time of and after giving effect to the proposed Restricted
     Payment (the amount of any such Restricted Payment, if other than in cash,
     shall be the Fair Market Value of the asset or assets proposed to be
     transferred by the Company or such Restricted Subsidiary, as the case may
     be, pursuant to such Restricted Payment),

     (A) no Default shall have occurred and be continuing,

     (B) the aggregate amount of such Restricted Payment and all other
     Restricted Payments declared or made from and after the Issue Date would
     not exceed the sum of

          (1) 50% of the aggregate Consolidated Net Income of the Company
          accrued on a cumulative basis during the period (treated as one
          accounting period) beginning on the Issue Date and ending on the last
          day of the fiscal quarter of the Company immediately preceding the
          date of such proposed Restricted Payment (or, if such aggregate
          cumulative Consolidated Net Income of the Company for such period
          shall be a deficit, minus 100% of such deficit) plus

          (2) the aggregate net cash proceeds received by the Company either (x)
          as capital contributions in the form of common equity to the Company
          after the Issue Date or (y) from the issuance or sale of Capital Stock
          (excluding Redeemable Capital Stock but including Capital Stock issued
          upon the conversion of convertible Indebtedness, in exchange for
          outstanding Indebtedness or from the exercise of options, warrants or
          rights to purchase Capital Stock (other than Redeemable Capital
          Stock)) of the Company to any person (other than to a Restricted
          Subsidiary or to an employee stock ownership plan or

                                       86
<PAGE>
 
          to a trust established by the Company or any of its Subsidiaries for
          the benefit of their employees) after the Issue Date plus

          (3) the aggregate net cash proceeds received by the Company from the
          issuance or sale subsequent to the Issue Date of its Capital Stock
          (other than Redeemable Capital Stock) to an employee stock ownership
          or stock purchase plan, provided, however, that if such employee stock
          ownership or stock purchase plan incurs any Indebtedness with respect
          thereto, such aggregate amount shall be limited to an amount equal to
          any increase in the consolidated net worth of the Company resulting
          from principal repayments made by such employee stock ownership or
          stock purchase plan with respect to such Indebtedness plus

          (4) in the case of the disposition or repayment of any Investment
          constituting a Restricted Payment made after the Issue Date (excluding
          any Investment made pursuant to clause (iv) of Section 1009(b), an
          amount equal to the lesser of the return of capital with respect to
          such investment and the initial amount of such Investment, in either
          case, less the cost of the disposition of such Investment plus

          (5) 100% of the aggregate amount of all Investments previously made on
          or after the date of the Indenture in any Unrestricted Subsidiary upon
          the revocation of the designation of such Unrestricted Subsidiary as
          such, other than Investments made in such Unrestricted Subsidiary
          pursuant to clause (iv) of Section 1009(b) and

     (C) the Company could incur $1.00 of additional Indebtedness under Section
         1008(a).

For purposes of the preceding clause (B)(2), upon the issuance of Capital Stock
either from the conversion of convertible Indebtedness or in exchange for
outstanding Indebtedness or upon the exercise of options, warrants or rights,
the amount counted as net cash proceeds received will be the cash amount
received by the Company at the original issuance of the Indebtedness that is so
converted or exchanged or from the issuance of options, warrants or rights, as
the case may be, plus the incremental amount of cash received by the Company, if
any, upon the conversion, exchange or exercise thereof.

     (b) None of the foregoing provisions of Section 1009(a) will prohibit (i)
the payment of any dividend within 60 days after the date of its declaration, if
at the date of declaration such payment would be permitted by Section 1009(a);
provided, however, that at the time of payment of such dividend, no other
Default shall have occurred and be continuing (or result therefrom); (ii) the
redemption, repurchase or other acquisition or retirement of any shares of any
class of Capital Stock of the Company or any Restricted Subsidiary in exchange
for, or out of the net cash proceeds of, a substantially concurrent issue and
sale of other shares of Capital Stock (other than Redeemable Capital Stock) of
the Company to any person (other than to a Restricted Subsidiary or an employee
stock ownership plan or to a trust established by the Company or any of its
Subsidiaries for the benefit of their employees); provided that such net cash
proceeds are excluded from clause (B)(2)(y) of Section 1009(a); (iii) so long as
no Default shall have occurred and be continuing, any redemption, repurchase or
other acquisition or retirement of Subordinated Obligations by exchange for, or
out of the net cash proceeds of, a substantially concurrent issue and sale of
(1) Capital Stock (other than Redeemable Capital Stock) of the Company to any
person (other than to a Restricted Subsidiary or an employee stock ownership
plan or to a trust established by the Company or any of its Subsidiaries for the
benefit of their employees); provided that any such net cash proceeds are
excluded from clause (B)(2)(y) of Section 1009(a); or (2) Indebtedness of the
Company so long as such Indebtedness (x) is subordinated to the Securities in
the same manner and at least to the same extent as the Subordinated Obligations
being redeemed, repurchased, acquired or retired, (y) has no Stated Maturity
earlier than the 91st day after the Stated Maturity for the final scheduled
principal payment of the Securities and (z) is permitted to be incurred pursuant
to Section 1008; and (iv) the making of Investments constituting Restricted
Payments made after the Issue Date as a result of the

                                       87
<PAGE>
 
receipt of non-cash consideration from any Asset Sale made pursuant to and in
compliance with Section 1012.  In computing the amount of Restricted Payments
previously made for purposes of clause (B) of Section 1009(a), Restricted
Payments made under clauses (i) and (iv) of this Section 1009(b) shall be
included.

     Section 1010.  Limitation on Liens.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind against or upon any of the Company's or such Restricted Subsidiary's (as
the case may be) property or assets, whether now owned or acquired after the
date of the Indenture, or any proceeds therefrom, which secures either (i)
Subordinated Obligations (other than Subordinated Obligations of a Restricted
Subsidiary owing to the Company secured by assets of such Restricted
Subsidiary), unless the Securities or Guarantees, as the case may be, are
secured by a Lien on such property, assets or proceeds that is senior in
priority to the Liens securing such Subordinated Obligations or (ii) Pari Passu
Indebtedness unless the Securities or Guarantees, as the case may be, are
equally and ratably secured with the Liens securing such Pari Passu
Indebtedness.  This Section 1010 will not apply to any Lien securing Acquired
Indebtedness, provided that any such Lien extends only to the properties or
assets that were subject to such Lien prior to the related acquisition by the
Company or such Restricted Subsidiary and was not created, incurred or assumed
in contemplation of such transaction.

     (b) Notwithstanding the foregoing provisions of Section 1010(a), any Lien
granted by the Company or any Restricted Subsidiary to secure the Securities or
Guarantees, as the case may be, created pursuant to Section 1010(a) shall
provide by its terms that such Lien shall be automatically and unconditionally
released and discharged upon the release by the holders of the Indebtedness of
the Company or any Restricted Subsidiary described in Section 1010(a) of their
Lien (including any deemed release upon payment in full of all obligations under
such Indebtedness), at a time when (A) no other Pari Passu Indebtedness and
Subordinated Obligations of the Company or any Restricted Subsidiary has been
secured by such property or assets of the Company or any such Restricted
Subsidiary or (B) the holders of all such other Pari Passu Indebtedness and
Subordinated Obligations which is secured by such property or assets of the
Company or any such Restricted Subsidiary also release their Lien in such
property or assets (including any deemed release upon payment in full of all
obligations under such Indebtedness).

     Section 1011.  Purchase of Securities Upon a Change of Control.

     (a)  Upon the occurrence of a Change of Control (the date of such
occurrence, the "Change of Control Date"), the Company shall be obligated to
make an offer to purchase (a "Change of Control Offer") and shall, subject to
the provisions of this Section 1011 described below, purchase, on a Business Day
(the "Change of Control Purchase Date") not more than 60 nor less than 30 days
following the occurrence of the Change of Control, all of the then outstanding
Securities at a purchase price equal to 101% of the principal amount thereof
plus accrued and unpaid interest, if any (the "Change of Control Purchase
Price"), to the Change of Control Purchase Date.  The Company shall, subject to
the provisions of this Section 1011 described below, purchase all Securities
properly tendered into the Change of Control Offer and not withdrawn.  Prior to
the mailing of the notice to Holders provided for below, the Company shall have
(i) terminated all commitments and repaid in full all Indebtedness under the
Credit Facility or (ii) obtained the requisite consents under the Credit
Facility to permit the purchase of the Securities as provided for under this
Section 1011.  If a notice has been mailed when such condition precedent has not
been satisfied, the Company shall have no obligation to (and shall not) effect
the purchase of the Securities until such time as such condition precedent is
satisfied.  Failure to mail the notice on the date specified below or to have
satisfied the foregoing condition precedent by the date that the notice is
required to be mailed shall in any event constitute a Default under Section
501(c)(iv).

                                       88
<PAGE>
 
     (b) Notice of a Change of Control Offer shall be mailed by the Company not
later than the 30th day after the Change of Control Date to each Holder of the
Securities at such Holder's addresses appearing in the Security Register (a
"Change of Control Purchase Notice"), with a copy to the Trustee and the Paying
Agent.  The Change of Control Offer shall remain open from the time of mailing
for at least 20 Business Days and until 5:00 p.m., New York City time, on the
Change of Control Purchase Date.  The notice, which shall govern the terms of
the Change of Control Offer, shall include such disclosures as are required by
law and shall state:

     Quarterly Report (or if the Company is not required to prepare any of the
     foregoing Forms, the comparable information required to be prepared by the
     Company and any Guarantor pursuant to Section 1019(a)), (ii) a description
     of material developments, if any, in the Company's business subsequent to
     the date of the latest of such reports and (iii) such other information, if
     any, concerning the business of the Company which the Company in good faith
     believes will enable such Holders to make an informed investment decision
     regarding the Change of Control Offer;

          (4) that the Change of Control Offer is being made pursuant to this
     Section 1011 and that all Securities properly tendered pursuant to the
     Change of Control Offer will be accepted for payment at the Change of
     Control Purchase Price;

          (5) the Change of Control Purchase Date, which shall be a Business Day
     fixed by the Company which shall be no earlier than 30 days nor later than
     60 days following the date of the occurrence of the Change of Control, or
     such later date as is necessary to comply with requirements under the
     Exchange Act;

          (6) the Change of Control Purchase Price;

          (7) the names and addresses of the Paying Agent and the offices or
     agencies referred to in Section 1002;

          (8) that Securities must be surrendered prior to the Change of Control
     Purchase Date to the Paying Agent at the office of the Paying Agent or to
     an office or agency referred to in Section 1002 to collect payment;

          (9) that the Change of Control Purchase Price for any Security which
     has been properly tendered and not withdrawn will be paid promptly
     following the Change of Control Purchase Date;

          (10) the procedures that a Holder must follow to accept a Change of
     Control Offer or to withdraw such acceptance;

          (11) that any Security not tendered will continue to accrue interest:
     and

                                       89
<PAGE>
 
     (12) that, unless the Company defaults in the payment of the Change of
     Control Purchase Price, any Securities accepted for payment pursuant to the
     Change of Control Offer shall cease to accrue interest after the Change of
     Control Purchase Date.

     (c) Upon receipt by the Company of the proper tender of Securities, the
Holder of the Security in respect of which such proper tender was made shall
(unless the tender of such Security is properly withdrawn) thereafter be
entitled to receive solely the Change of Control Purchase Price with respect to
such Security.  Upon surrender of any such Security for purchase in accordance
with the foregoing provisions, such Security shall be paid by the Company at the
Change of Control Purchase Price; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Change of Control Purchase
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such on the relevant Regular Record Dates
according to the terms and the provisions of Section 309.  If any Security
tendered for purchase in accordance with the provisions of this Section 1011
shall not be so paid upon surrender thereof, the principal thereof (and premium,
if any, thereon) shall, until paid, bear interest from the Change of Control
Purchase Date at the rate borne by such Security.  Holders electing to have
Securities purchased will be required to surrender such Securities to the Paying
Agent at the address specified in the Change of Control Purchase Notice on or
prior to the Change of Control Purchase Date.  Any Security that is to be
purchased only in part shall be surrendered to a Paying Agent at the office of
such Paying Agent (with, if the Company, the Security Registrar or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Security Registrar or the Trustee, as the
case may be, duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing), and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge,
one or more new Securities of any authorized denomination as requested by such
Holder in an aggregate principal amount equal to, and in exchange for, the
portion of the principal amount of the Security so surrendered that is not
purchased.

     (d) The Company shall (i) not later than the Change of Control Purchase
Date, accept for payment Securities or portions thereof tendered pursuant to the
Change of Control Offer, (ii) not later than 10:00 a.m. (New York time) on the
Business Day following the Change of Control Purchase Date, deposit with the
Trustee or with a Paying Agent an amount of money in same day funds (or New York
Clearing House funds if such deposit is made prior to the Change of Control
Purchase Date) sufficient to pay the aggregate Change of Control Purchase Price
of all the Securities or portions thereof which are to be purchased as of the
Change of Control Purchase Date and (iii) not later than 10:00 a.m. (New York
time) on the Business Day following the Change of Control Purchase Date, deliver
to the Paying Agent an Officers' Certificate stating the Securities or portions
thereof accepted for payment by the Company.  The Paying Agent shall promptly
mail or deliver to Holders of Securities so accepted payment in an amount equal
to the Change of Control Purchase Price of the Securities purchased from each
such Holder, and the Company shall execute and the trustee shall promptly
authenticate and mail or deliver to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered.  Any
Securities not so accepted shall be promptly mailed or delivered by the Paying
Agent at the Company's expense to the Holder thereof.  The Company will publicly
announce the results of the Change of Control Offer on the Change of Control
Purchase Date.  For purposes of this Section 1011, the Company shall choose a
Paying Agent which shall not be the Company.

     (e) A tender made in response to a Change of Control Purchase Notice may be
withdrawn if the Company receives, not later than one Business Day prior to the
Change of Control Purchase Date, a telegram, telex, facsimile transmission or
letter, specifying, as applicable:

          (1)  the name of the Holder;

          (2) the certificate number of the Security in respect of which such
     notice of withdrawal is being submitted;

<PAGE>
 
          (3) the principal amount of the Security (which shall be $1,000 or an
     integral multiple thereof) delivered for purchase by the Holder as to which
     such notice of withdrawal is being submitted;

          (4) a statement that such Holder is withdrawing his election to have
     such principal amount of such Security purchased; and

          (5) the principal amount, if any, of such Security (which shall be
     $1,000 or an integral multiple thereof) that remains subject to the
     original Change of Control Purchase Notice and that has been or will be
     delivered for purchase by the Company.

     (f) Subject to applicable escheat laws, the Trustee and the Paying Agent
shall return to the Company any cash that remains unclaimed, together with
interest or dividends, if any, thereon, held by them for the payment of the
Change of Control Purchase Price; provided, however, that, (i) to the extent
that the aggregate amount of cash deposited by the Company pursuant to clause
(ii) of Section 1011(d) exceeds the aggregate Change of Control Purchase Price
of the Securities or portions thereof to be purchased, then the Trustee shall
hold such excess for the Company and (ii) unless otherwise directed by the
Company in writing, no later than the second Business Day following the Change
of Control Purchase Date the Trustee shall return any such excess (including,
without limitation, monies deposited with respect to a tender withdrawn in
accordance with the provisions of Section 1011(e)) to the Company together with

     Section 1012.  Disposition of Proceeds of Asset Sales.

     (a) The Company will not, and will not permit any of the Restricted
Subsidiaries to, directly or indirectly, make any Asset Sale unless (i) the
Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the shares, properties or assets sold or otherwise disposed of and (ii)
with respect to any Asset Sale for which the consideration exceeds $5,000,000,
at least 75% of such consideration consists of cash and/or Cash Equivalents
(with Indebtedness of the Company or any Restricted Subsidiary (other than any
Restricted Subsidiary that will cease to be a Restricted Subsidiary as a result
of such Asset Sale) being counted as cash for all purposes of this Section
1012(a) if the Company or the Restricted Subsidiary is unconditionally released
from any liability therefor).  Net Cash Proceeds of any Asset Sale may be
applied to repay Specified Indebtedness or Credit Facility Obligations (but only
if the commitments or amounts available to be borrowed under such Specified
Indebtedness or the Credit Facility, as the case may be, are permanently reduced
by the amount of such payment).  To the extent that such Net Cash Proceeds are
not applied as provided in the preceding sentence, the Company or a Restricted
Subsidiary, as the case may be, may apply the Net Cash Proceeds from such Asset
Sale, within 360 days of the date of such Asset Sale, to an investment in
properties and assets that were the subject of such Asset Sale or in properties
and assets that are similar to the properties and assets that will be used in
the business of the Company and the Restricted Subsidiaries existing on the
Issue Date or in businesses reasonably related thereto ("Replacement Assets").
Any Net Cash Proceeds from any Asset Sale not applied as provided in the
preceding two sentences, within 360 days of the date of such Asset Sale,
constitute "Excess Proceeds" subject to disposition as provided below.

     (b) When the aggregate amount of Excess Proceeds equals or exceeds
$10,000,000, the Company shall make an offer to purchase, from all Holders of
the Securities and any then outstanding Pari Passu Indebtedness required to be
repurchased or repaid on a permanent basis in connection with

                                       91
<PAGE>
 
an Asset Sale, an aggregate principal amount of Securities and any such Pari
Passu Indebtedness equal to such Excess Proceeds as follows:

          (i) (a) The Company shall make an offer to purchase (a "Net Proceeds
     Offer") from all Holders of the Securities in accordance with the
     procedures set forth in the Indenture the maximum principal amount
     (expressed as a multiple of $1,000) of Securities that may be purchased out
     of an amount (the "Payment Amount") equal to the product of such Excess
     Proceeds multiplied by a fraction, the numerator of which is the
     outstanding principal amount of the Securities and the denominator of which
     is the sum of the outstanding principal amount of the Securities and such
     Pari Passu Indebtedness, if any (subject to proration if such amount is
     less than the aggregate Offered Price (as defined in clause (ii) below) of
     all Securities tendered), and (b) to the extent required by any such Pari
     Passu Indebtedness and provided there is a permanent reduction in the
     principal amount of such Pari Passu Indebtedness, the Company shall make an
     offer to purchase such Pari Passu Indebtedness (a "Pari Passu Offer") in an
     amount (the "Pari Passu Indebtedness Amount") equal to the excess of the
     Excess Proceeds over the Payment Amount.

          (ii) The offer price for the Securities shall be payable in cash in an
     amount equal to 100% of the principal amount of the Securities tendered
     pursuant to a Net Proceeds Offer, plus accrued and unpaid interest, if any,
     to the date ("Offer Date") such Net Proceeds Offer is consummated (the
     "Offered Price"), in accordance with the procedures set forth in this
     Indenture.  To the extent that the aggregate Offered Price of the
     Securities tendered pursuant to a Net Proceeds Offer is less than the
     Payment Amount relating thereto or the aggregate amount of the Pari Passu
     Indebtedness that is purchased or repaid pursuant to the Pari Passu Offer
     is less than the Pari Passu Indebtedness Amount (such shortfall
     constituting a "Net Proceeds Deficiency"), the Company may use such Net
     Proceeds Deficiency, or a portion thereof, for general corporate purposes,
     subject to the limitations of Section 1009.

          (iii) If the aggregate Offered Price of Securities validly tendered
     and not withdrawn by holders thereof exceeds the Payment Amount, Securities
     to be purchased will be selected on a pro rata basis.  Upon completion of
     such Net Proceeds Offer and Pari Passu Offer, the amount of Excess Proceeds
     shall be reset to zero.

     (c) When the aggregate amount of Excess Proceeds exceeds $10,000,000, such
Excess Proceeds will, prior to any purchase of Securities described in Section
1012(b), be set aside by the Company in a separate account pending (i) deposit
with the depository or a paying agent of the amount required to purchase the
Securities tendered in a Net Proceeds Offer or Pari Passu Indebtedness tendered
in a Pari Passu Offer, (ii) delivery by the Company of the Offered Price to the
holders of the Securities tendered in a Net Proceeds Offer or Pari Passu
Indebtedness tendered in a Pari Passu Offer and (iii) application, as set forth
above, of Excess Proceeds in the business of the Company and its Subsidiaries
for general corporate purposes.  Such Excess Proceeds may be invested in Cash
Equivalents, provided that the maturity date of any such investment made after
the amount of Excess Proceeds exceeds $10,000,000 shall not be later than the
Offer Date.  The Company shall be entitled to any interest or dividends accrued,
earned or paid on such Temporary Cash Investments; provided that the Company
shall not withdraw such interest from the separate account if an Event of
Default has occurred and is continuing.

     (d) If the Company becomes obligated to make a Net Proceeds Offer pursuant
to Section 1012(b), the Securities and the Pari Passu Indebtedness shall be
purchased by the Company, at the option of the holders thereof, in whole or in
part in integral multiples of $1,000, on a date that is not earlier than 45 days
and not later than 60 days from the date the notice of the Net Proceeds Offer is
given to holders, or such later date as may be necessary for the Company to
comply with the requirements under the Exchange Act.

                                       92
<PAGE>
 
     (e) The Company will comply with the applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, and any other applicable securities
laws or regulations in connection with a Net Proceeds Offer.

     (f) Subject to Section 1012(e), within 30 days after the date on which the
amount of Excess Proceeds equals or exceeds $10,000,000, the Company shall send
or cause to be sent by first-class mail, postage prepaid, to the Trustee and to
each Holder, at his address appearing in the Security Register, a notice stating
or including:

          (1) that the Holder has the right to require the Company to
     repurchase, subject to proration, such Holder's Securities at the Offered
     Price;

          (2)  the Offer Date;

          (3) the instructions a Holder must follow in order to have his
     Securities purchased in accordance with Section 1012(b);

          (4) (i) the most recently filed Annual Report on Form 10-K (including
     audited consolidated financial statements) of the Company, the most recent
     subsequently filed Quarterly Report on Form 10-Q, as applicable, and any
     Current Report on Form 8-K of the Company filed subsequent to such
     Quarterly Report, other than Current Reports describing Asset Sales
     otherwise described in the offering materials (or corresponding successor
     reports) (or if the Company is not required to prepare any of the foregoing
     Forms, the comparable information required pursuant to Section 1019(a)),
     (ii) a description of material developments, if any, in the Company's
     business subsequent to the date of the latest of such Reports, (iii) if
     material, appropriate pro forma financial information, and (iv) such other
     information, if any, concerning the business of the Company which the
     Company in good faith believes will enable such Holders to make an informed
     investment decision regarding the Offer;

          (5)  the Offered Price;

          (6) the names and addresses of the Paying Agent and the offices or
     agencies referred to in Section 1002;

          (7) that Securities must be surrendered prior to the Offer Date to the
     Paying Agent at the office of the Paying Agent or to an office or agency
     referred to in Section 1002 to collect payment;

          (8) that any Securities not tendered will continue to accrue interest
     and that unless the Company defaults in the payment of the Offered Price,
     any Security accepted for payment pursuant to the Offer shall cease to
     accrue interest on and after the Offer Date;

          (9) the procedures for withdrawing a tender; and

          (10) that the Offered Price for any Security which has been properly
     tendered and not withdrawn and which has been accepted for payment pursuant
     to the Offer will be paid promptly following the Offer Date.

     (g) Holders electing to have Securities purchased hereunder will be
required to surrender such Securities at the address specified in the notice on
or prior to the Offer Date.  Holders will be entitled to withdraw their election
to have their Securities purchased pursuant to this Section 1012, if the Company
receives, not later than the Offer Date, a telegram, telex, facsimile
transmission or letter setting forth (1) the name of the Holder, (2) the
certificate number of the Security in respect of which such notice

                                       93
<PAGE>
 
of withdrawal is being submitted, (3) the principal amount of the Security
(which shall be $1,000 or an integral multiple thereof) delivered for purchase
by the Holder as to which his election is to be withdrawn, (4) a statement that
such Holder is withdrawing his election to have such principal amount of such
Security purchased, and (5) the principal amount, if any, of such Security
(which shall be $l,000 or an integral multiple thereof) that remains subject to
the original notice of the Offer and that has been or will be delivered for
purchase by the Company.

     (h) The Company shall (i) not later than the Offer Date, accept for payment
Securities or portions thereof tendered pursuant to the Offer, (ii) not later
than 10:00 a.m. (New York time) on the Business Day following the Offer Date,
deposit with the Trustee or with a Paying Agent an amount of money in same day
funds (or New York Clearing House funds if such deposit is made prior to the
Offer Date) sufficient to pay the aggregate Offered Price of all the Securities
or portions thereof which are to be purchased on that date and (iii) not later
than 10:00 a.m. (New York time) on the Business Day following the Offer Date,
deliver to the Paying Agent an Officers' Certificate stating the Securities or
portions thereof accepted for payment by the Company.  The Paying Agent shall
promptly mail or deliver to Holders of Securities so accepted payment in an
amount equal to the Offered Price of the Securities purchased from each such
Holder, and the Company shall execute and the Trustee shall promptly
authenticate and mail or deliver to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered.  Any
Securities not so accepted shall be promptly mailed or delivered by the Paying
Agent at the Company's expense to the Holder thereof.  For purposes of this
Section 1012, the Company shall choose a Paying Agent which shall not be the
Company.

     (i) Subject to applicable escheat laws, the Trustee and the Paying Agent
shall return to the Company any cash that remains unclaimed, together with
interest, if any, thereon held by then for the payment of the Offered Price;
provided, however, that (x) to the extent that the aggregate amount of cash
deposited by the Company with the Trustee in respect of a Net Proceeds Offer
exceeds the aggregate Offered Price of the Securities or portions thereof to be
purchased, then the Trustee shall hold such excess for the Company and (y)
unless otherwise directed by the Company in writing, no later than the second
Business Day following the Offer Date the Trustee shall return any such excess
(including, without limitation, monies deposited with respect to an election
which has been withdrawn in accordance with Section 1012(g)) to the Company
together with interest or dividends, if any, thereon.

     (j) Securities to be purchased shall, on the Offer Date, become due and
payable at the Offered Price and from and after such date (unless the Company
shall default in the payment of the Offered Price) such Securities shall cease
to bear interest.  Such Offered Price shall be paid to such Holder promptly
following the later of the Offer Date and the time of delivery of such Security
to the relevant Paying Agent at the office of such Paying Agent by the Holder
thereof in the manner required.  Upon surrender of any such Security for
purchase in accordance with the foregoing provisions, such Security shall be
paid by the Company at the Offered Price; provided, however, that installments
of interest whose Stated Maturity is on or prior to the Offer Date shall be
payable to the person in whose name the Securities (or any Predecessor
Securities) are registered as such on the relevant Regular Record Dates
according to the terms and the provisions of Section 309: provided, further,
that Securities to be purchased are subject to proration if the Excess Proceeds
are less than the aggregate Offered Price of all Securities tendered for
purchase, with such adjustments as may be appropriate by the Trustee so that
only Securities in denominations of $1,000 or integral multiples thereof, shall
be purchased.  If any Security tendered for purchase shall not be so paid upon
surrender thereof by deposit of funds with the Trustee or a Paying Agent in
accordance with Section 1012(g), the principal thereof (and premium, if any,
thereon) shall, until paid, bear interest from the Offer Date at the rate borne
by such Security.  Any Security that is to be purchased only in part shall be
surrendered to a Paying Agent at the office of such Paying Agent (with, if the
Company, the Security Registrar or the Trustee so requires, due endorsement by,
or a written instrument of transfer in form satisfactory to the Company and the
Security Registrar or the Trustee duly executed by, the Holder thereof or such
Holder's attorney duly authorized in writing), and the Company shall execute and
the Trustee shall authenticate and deliver to the Holder of such

                                       94
<PAGE>
 
Security, without service charge, one or more new Securities of any authorized
denomination as requested by such Holder in an aggregate principal amount equal
to, and in exchange for, the portion of the principal amount of the Security so
surrendered that is not purchased.  The Company shall publicly announce the
results of the Offer on or as soon as practicable after the Offer Date.

     Section 1013.  Limitation on Sale, Issuance and Ownership of Capital Stock
of Restricted Subsidiaries.

     The Company (i) will not, directly or indirectly, sell or otherwise dispose
of any shares of Capital Stock of a Restricted Subsidiary, (ii) will not permit
any of the Restricted Subsidiaries, directly or indirectly, to issue or sell or
otherwise dispose of any Capital Stock (other than (A) to the Company or a
Wholly-Owned Restricted Subsidiary or (B) to the extent such shares represent
directors' qualifying shares or shares required by applicable law to be held by
a person other than the Company or a Wholly-Owned Subsidiary), (iii) will not
permit any person (other than the Company or a Wholly-Owned Restricted
Subsidiary), directly or indirectly, to own any Capital Stock of any Restricted
Subsidiary except for Capital Stock of a Restricted Subsidiary issued and
outstanding at the time such Restricted Subsidiary became a Subsidiary of the
Company; provided that such Capital Stock was not issued in anticipation of such
person becoming a Subsidiary of the Company and (iv) will not permit any person,
directly or indirectly, to acquire Capital Stock of any Restricted Subsidiary
from the Company or any Wholly-Owned Restricted Subsidiary except upon the
acquisition of all the outstanding Capital Stock of such Restricted Subsidiary
in accordance with the terms of the Indenture.

     Section 1014.  Limitation on Transactions with Affiliates.

     The Company will not, and will not permit any of the Restricted
Subsidiaries to, directly or indirectly, enter into or suffer to exist any
transaction or series of related transactions (including, without limitation,
the sale, transfer, disposition, purchase, exchange or lease of assets, property
or services, employee compensation arrangements or the rendering of any service)
with, or for the benefit of, any Affiliate of the Company (other than a Wholly-
Owned Restricted Subsidiary) except (i) on terms that are no less favorable to
the Company or the Restricted Subsidiary, as the case may be, than those which
could have been obtained in a comparable transaction at such time from persons
who do not have such a relationship with the Company, (ii) with respect to any
transaction or series of related transactions involving aggregate payments or
value equal to or greater than $2,000,000, the terms of such transaction or
transactions, as the case may be, shall be set forth in writing and the Company
shall have delivered an Officer's Certificate to the Trustee certifying that
such transaction or series of related transactions comply with the preceding
clause (i), and (iii) with respect to any transaction or series of related
transactions involving aggregate payments or value equal to or greater than
$5,000,000, the terms of such transaction or transactions, as the case may be,
shall be set forth in writing and the Company shall have delivered an Officer's
Certificate to the Trustee certifying that such transaction or series of
transactions (A) comply with the preceding clause (i) and (B) have been approved
by a majority of the Board of Directors of the Company, including a majority of
the Disinterested Directors of the Board of Directors of the Company, or in lieu
of the certification required by the preceding clause (B), the Company shall
have delivered to the Trustee a written opinion of an investment banking firm of
national standing or other recognized independent expert with experience
appraising the terms and conditions of the type of transaction or series of
related transactions for which its opinion is being delivered stating that the
transaction or series of related transactions is fair to the Company or such
Restricted Subsidiary from a financial point of view.  For the purposes of the
foregoing, a director of the Company shall not be considered "interested" with
respect to a transaction solely by virtue of being a director of the other party
to such transaction.  This Section 1014 will not restrict the Company from (a)
making dividends permitted by Section 1009, (b) paying reasonable and customary
regular fees to directors of the Company who are not employees of the Company,
(c) making loans or advances to officers of the Company and the Restricted
Subsidiaries in the ordinary course of business for bona fide business purposes
of the Company in an aggregate principal amount not to exceed $1,000,000
outstanding at any one time and (d) the

                                       95
<PAGE>
 
Company's employee compensation and other benefit arrangements existing on the
Issue Date or thereafter entered into by the Company or any Restricted
Subsidiary in the ordinary course of business.

     Section 1015.  Limitation on Dividends and Other Payment Restrictions
Affecting Restricted Subsidiaries.

     The Company will not, and will not permit any of the Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (a) pay dividends, in cash or otherwise,
or make any other distributions on or in respect of its Capital Stock or any
other interest or participation in, or measured by, its profits, (b) pay any
Indebtedness owed to the Company or any other Restricted Subsidiary, (c) make
loans or advances to the Company or any other Restricted Subsidiary or (d)
transfer any of its properties or assets to the Company or any other Restricted
Subsidiary (other than any customary restriction on transfers of property
subject to a Lien permitted under this Indenture (other than a Lien on cash not
constituting proceeds of non-cash property subject to a Lien permitted under
this Indenture)), except for such encumbrances or restrictions existing under or
by reason of (i) the mandatory provisions of general applicability of applicable
law or governmental regulation, (ii) customary non-assignment provisions of any
contract or any licensing agreement entered into by the Company or any of the
Restricted Subsidiaries in the ordinary course of business or any lease
governing a leasehold interest of the Company or any Restricted Subsidiary,
(iii) any agreement or other instrument of a person acquired by the Company or
any Restricted Subsidiary in existence at the time of such acquisition (but not
created in contemplation thereof), which encumbrance or restriction is not
applicable to any person, or the properties or assets of any person, other than
the person, or the property or assets (including subsequently acquired property
or assets to the extent subject thereto) of the person, so acquired, (iv) any
encumbrance or restriction in the Credit Facility or any other agreement, in
each case, as in effect on the Issue Date and listed in Schedule 1015 hereto, or
otherwise modified from time to time; provided that any such modification is no
less favorable to the holders of Securities (as determined by the Board of
Directors of the Company) than the applicable provision as in effect on the
Issue Date and (v) any encumbrance or restriction pursuant to any agreement that
extends, restructures, refinances, renews, refunds or replaces any agreement
described in clause (ii), (iii) or (iv) of this Section 1015, which is no less
favorable to the holders of Securities (as determined by the Board of Directors
of the Company) than those existing under the agreement being extended,
restructured, refinanced, renewed, refunded or replaced.

     Section 1016.  Limitation on Certain Senior Subordinated Obligations.

     The Company will not, and will not permit any Guarantor or Restricted
Subsidiary which is not a Guarantor to, directly or indirectly, create, incur,
issue, assume, guarantee or otherwise in any manner become directly or
indirectly liable for or with respect to or otherwise permit to exist any
Indebtedness which is expressly subordinate or junior in right of payment in any
respect to any Indebtedness of the Company or such Guarantor or Restricted
Subsidiary which is not a Guarantor, as the case may be, unless such
Indebtedness ranks pari passu in right of payment with the Securities or the
Guarantee of such Guarantor, or is expressly subordinated in right of payment to
the Securities or such Guarantee at least to the same extent as the Securities
or such Guarantee are subordinate in right of payment to Senior Indebtedness or
Guarantor Senior Indebtedness, as the case may be.

     Section 1017.  Limitations on Designation of Unrestricted Subsidiaries.

     (a) The Company may, pursuant to resolution of its Board of Directors,
designate any Subsidiary of the Company as an "Unrestricted Subsidiary" under
this Indenture (a "Designation") only if:

                                       96
<PAGE>
 
          (i) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Designation;

          (ii) the Company would be permitted under this Indenture to make an

     Market Value of the Capital Stock of such Subsidiary on such date;

          (iii)  the Company would be permitted under this Indenture to incur
     $1.00 of additional Indebtedness pursuant to Section 1008(a) at the time of
     Designation (assuming the effectiveness of such Designation);

          (iv) with respect to the Subsidiary to be designated an Unrestricted
     Subsidiary, each of the Company and its Subsidiaries, other than the
     Subsidiary to be designated an Unrestricted Subsidiary, is in compliance
     with the provisions of clauses (x), (y) and (z) of the next following
     clause (v) as if such Subsidiary to be so designated had been and is an
     Unrestricted Subsidiary for all purposes of such clauses, at the time of,
     and after giving effect to, such Designation (assuming the effectiveness of
     such Designation); and

          (v) the Subsidiary to be designated an Unrestricted Subsidiary, or any
     Subsidiary thereof, owns no Capital Stock or Indebtedness of, owes no
     Indebtedness to, or holds no Lien on any property of, the Company or any
     other Subsidiary of the Company that is not a Subsidiary of the Subsidiary
     to be so designated at the time of or after giving effect to such
     Designation (assuming the effectiveness of such Designation).

     (b) In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
1009 for all purposes of this Indenture in the Designation Amount.  The Company
shall not and shall not permit any Restricted Subsidiary to, directly or
indirectly, at any time (x) provide credit support for, or a guarantee of, any
Indebtedness of any Unrestricted Subsidiary (including any undertaking,
agreement or instrument evidencing such Indebtedness), (y) be directly or
indirectly liable for any Indebtedness of an Unrestricted Subsidiary or (z) be
directly or indirectly liable for any Indebtedness which provides that the
holder thereof may (upon notice, lapse of time or both) declare a default
thereon or cause the payment thereof to be accelerated or payable prior to its
final scheduled maturity upon the occurrence of a default with respect to any
Indebtedness of any Unrestricted Subsidiary (including any right to take
enforcement action against such Unrestricted Subsidiary), except in the case of
clause (x) or (y) of this Section 1017(b) to the extent permitted under Section
1009.

     (c) The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

          (i) no Default shall have occurred and be continuing at the time of
     and after giving effect to such Revocation; and

          (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately following such Revocation would, if incurred at
     such time, have been permitted to be incurred for all purposes of the
     Indenture.

     (d) All Designations and Revocations must be evidenced by Board Resolutions
of the Company delivered to the Trustee certifying compliance with the foregoing
provisions.

     Section 1018.  Limitation on Non-Guarantor Restricted Subsidiaries.

     (a) The Company will not permit any Restricted Subsidiary, other than the
Guarantors, directly or indirectly, to secure the payment of any Senior
Indebtedness, and the Company will not, and will not permit any Restricted
Subsidiary to, pledge any intercompany notes representing obligations of any
Restricted Subsidiary (other than the Guarantors) to secure the payment of any
Senior Indebtedness, unless in each case such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to the Indenture
providing for a guarantee of payment of the Securities by such Restricted
Subsidiary, which guarantee shall be on the same terms as the guarantee of the
Senior Indebtedness (if a guarantee of Senior Indebtedness is granted by any
such Restricted Subsidiary) except that the guarantee of the Securities need not
be secured and shall be subordinated to the claims against such Restricted
Subsidiary in respect of Senior Indebtedness to the same extent as the
Securities are subordinated to Senior Indebtedness under this Indenture.

     (b) The Company will not permit any Restricted Subsidiary which is not a
Guarantor to incur any Indebtedness (other than Acquired Indebtedness) or
guarantee the payment of any Indebtedness of the Company or any other Restricted
Subsidiary unless (i) such Restricted Subsidiary simultaneously executes and
delivers a supplemental indenture to this Indenture providing for a Guarantee of
the Securities by such Restricted Subsidiary, which Guarantee will be
subordinated to Guarantor Senior Indebtedness (but no other Indebtedness) to the
same extent that the Securities are subordinated to Senior Indebtedness and
(ii), with respect to any guarantee of Subordinated Obligations by a Restricted
Subsidiary, any such guarantee shall be subordinated to such Restricted
Subsidiary's Guarantee at least to the same extent as such Subordinated
Obligations is subordinated to the Securities.

     (c) With respect to each supplemental indenture to this Indenture delivered
pursuant to Section 1018(a) and Section 1018(b), (i) each such Restricted
Subsidiary shall waive, and agree not in any manner whatsoever to claim to take
the benefit or advantage of, any rights of reimbursement, indemnity or
subrogation or any other rights against the Company or any other Restricted
Subsidiary as a result of any payment by such Restricted Subsidiary under its
Guarantee until such time as the obligations guaranteed thereby are paid in full
and (ii) such Restricted Subsidiary shall deliver to the Trustee an Opinion of
Independent Counsel to the effect that such Guarantee has been duly executed and
authorized and constitutes a valid, binding and enforceable obligation of such
Restricted Subsidiary, except insofar as enforcement thereof may be limited by
bankruptcy, insolvency or similar laws (including, without limitation, all laws
relating to fraudulent transfer and fraudulent conveyances) and except insofar
as enforcement thereof is subject to general principles of equity.

     (d) Subject to the requirements (if any) described under Article Eight, any
Guarantee by a Restricted Subsidiary of the Securities shall be automatically
and unconditionally released and discharged (i) upon any sale, exchange or
transfer, to any person not an Affiliate of the Company, of all of the Company's
Capital Stock in, or all or substantially all the assets of, such Restricted
Subsidiary, which transaction is in compliance with the terms of the Indenture
(including compliance with Section 1012 in respect thereto and the providing, in
connection therewith, by the Company to the Trustee of an Officer's Certificate
to the effect that the Company will comply with its obligations under Section
1012 in respect of any such dispositions) and such Restricted Subsidiary is
released from all guarantees and other security, if any, by it of other
Indebtedness of the Company or any Restricted Subsidiaries or (ii) at the
request of the Company, if the holders of the Indebtedness of the Company or any
other Restricted Subsidiary, as the case may be, described in Section 1018(a)
and Section 1018(b) unconditionally release their guarantee or Lien, as the case
may be, of such Restricted Subsidiary (including any deemed release upon payment
in full of all obligations under such Indebtedness), such release and discharge
to be effective at such time as, and for such periods that, (A) no other
Indebtedness of the Company or any other Restricted Subsidiary, as the case may
be, has been secured or guaranteed by such Restricted Subsidiary, as the case
may be, and (B) the holders of all such other Indebtedness which is guaranteed
by such Restricted Subsidiary also unconditionally release their guarantee by,
or Lien in assets or

                                       98

properties of, such Restricted Subsidiary (including any deemed release upon
payment in full of all obligations under such Indebtedness).

     Section 1019.  Reporting Requirements.

     (a) Whether or not the Company or any Guarantor is subject to Section 13(a)
or 15(d) of the Exchange Act, the Company and such Guarantor will, to the extent
permitted under the Exchange Act, file with the Commission the annual reports,
quarterly reports and other documents which the Company and such Guarantor would
have been required to file with the Commission pursuant to such Section 13(a) or
15(d) if the Company and such Guarantor were so subject, such documents to be
filed with the Commission on or prior to the date (the "Required Filing Date")
by which the Company and such Guarantor would have been required so to file such
documents if the Company and such Guarantor were so subject.  The Company and
such Guarantor will also in any event (i) within 30 days of each Required Filing
Date (A) transmit by mail to all Holders, as their names and addresses appear in
the Security Register, without cost to such Holders and (B) file with the
Trustee copies of the annual reports, quarterly reports and other documents
which the Company and such Guarantor would have been required to file with the
Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if the Company
and such Guarantor were subject to either of such Sections and (ii) if filing
such documents by the Company and such Guarantor with the Commission is not
permitted under the Exchange Act, promptly upon written request and payment of
the reasonable cost of duplication and delivery, supply copies of such documents
to any prospective Holder at the Company's and such Guarantor's cost.

     (b) The Company will deliver to the Trustee, on or before a date not more
than 60 days after the end of each fiscal quarter and not more than 120 days
after the end of each fiscal year of the Company ending after the date hereof, a
written statement signed by two executive officers of the Company, one of whom
shall be the principal executive officer, principal financial officer or
principal accounting officer of the Company, as to compliance herewith,
including whether or not, after a review of the activities of the Company and
each Guarantor during such year or such quarter and of the Company's and each
Guarantor's performance under this Indenture, to the best knowledge, based on
such review, of the signers thereof, no Default or Event of Default exists, or
if a Default exists, specifying the nature and status thereof and any actions
being taken by the Company and the Guarantors with respect thereto.

     (c) When any Default or Event of Default has occurred and is continuing, or
if the Trustee or any Holder or the trustee for or the holder of any other
evidence of Indebtedness of the Company or any Subsidiary gives any notice or
takes any other action with respect to a claimed default, the Company shall
deliver to the Trustee by registered or certified mail or facsimile transmission
followed by hard copy an Officers' Certificate specifying such Default, Event of
Default, notice or other action, the status thereof and what actions the Company
and the Guarantors are taking or propose to take with respect thereto, within 10
Business Days of its occurrence; provided, however, any Default based upon non-
compliance with the notification requirements of this Section 1019(c) may be (i)
expressly waived or (ii) cured if the event giving rise to the requirement for
such notification shall have been waived or cured, in each case, in accordance
with the terms of this Indenture.

     Section 1020.  Waiver of Certain Covenants.

     The Company and the Guarantors may omit in any particular instance to
comply with any covenant or condition set forth in Sections 1006 through 1010
and 1013 through 1019(a), if, before or after the time for such compliance, the
Holders of not less than a majority in aggregate principal amount of the
Securities at the time Outstanding shall, by Act of such Holders, waive such
compliance in such instance with such covenant or provision, but no such waiver
shall extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the

                                       99
<PAGE>
 
obligations of the Company and the duties of the Trustee in respect of any such
covenant or condition shall remain in full force and effect.

     Section 1021.  Waiver of Stay, Extension or Usury Laws.

     Each of the Company and the Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law which would prohibit or forgive the
Company or any Guarantor, as the case may be, from paying all or any portion of
the principal of, premium, if any, or interest on the Securities as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may
affect the covenants or the performance of this Indenture; and each of the
Company and the Guarantors hereby expressly waives (to the extent that it may
lawfully do so) all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                            REDEMPTION OF SECURITIES

     Section 1101.  Rights of Redemption.

     (a) The Securities are subject to redemption at any time on or December 15,
2002, at the option of the Company, in whole or in part, subject to the
conditions, and at the Redemption Prices, specified in the form of Security,
together with accrued and unpaid interest, if any, to the Redemption Date
(subject to the right of Holders of record on relevant Regular Record Dates and
Special Record Dates to receive interest due on relevant Interest Payment Dates
and Special Payment Dates).

     (b) At any time prior to December 1, 2000, the Company may, at its option,
use the net proceeds of one or more Public Equity Offerings to redeem up to an
aggregate of 35% of the aggregate principal amount of Securities originally
issued under this Indenture at a redemption price equal to 108.625% of the
aggregate principal amount thereof, plus accrued and unpaid interest thereon, if
any, to the redemption date; provided that at least $81,250,000 aggregate
principal amount of the Securities remains outstanding immediately after the
occurrence of such redemption.  In order to effect the foregoing redemption, the
Company must mail a notice of redemption no later than 30 days after the closing
of the related Public Equity Offering and must consummate such redemption within
60 days of the closing of the Public Equity Offering.

     Section 1102.  Applicability of Article.

     Redemption of Securities at the election of the Company or otherwise, as
permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article Eleven.

     Section 1103.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities pursuant to Section
1101 shall be evidenced by a Company Order and an Officers' Certificate.  In
case of any redemption at the election of the Company, the Company shall, not
less than 30 nor more than 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice period shall be satisfactory to the Trustee),
notify the Trustee in writing of such Redemption Date and of the principal
amount of Securities to be redeemed.

                                      100
<PAGE>
 
     Section 1104.  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities are to be redeemed at any time, the
particular Securities or portions thereof to be redeemed shall be selected not
more than 30 days prior to the Redemption Date.  The Trustee shall select the
Securities or portions thereof to be redeemed in compliance with any applicable
requirements of the principal national securities exchange, if any, on which the
Securities are listed or, if the Securities are not then listed on a national
securities exchange (or if the Securities are so listed but such exchange does
not impose requirements with respect to the selection of debt securities for
redemption), on a pro rata basis, by lot or by such method as the Trustee in its
sole discretion shall deem fair and appropriate.  The amounts to be redeemed
shall be equal to $1,000 or any integral multiple thereof.

     The Trustee shall promptly notify the Company and the Security Registrar in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to redemption of Securities shall relate, in the case of
any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security which has been or is to be redeemed.

     Section 1105.  Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 days nor more than 60 days prior to the Redemption Date,
to each Holder of Securities to be redeemed, at its address appearing in the
Security Register.  If the redemption is pursuant to Section 1101(b), notice of
redemption shall be mailed no later than 30 days after the closing of the
related Public Equity Offering.

     All notices of redemption shall state:

     (a)  the Redemption Date;

     (b)  the Redemption Price;

     (c) if less than all Outstanding Securities are to be redeemed, the
identification of the particular Securities to be redeemed;

     (d) in the case of a Security to be redeemed in part, the principal amount
of such Security to be redeemed and that after the Redemption Date upon
surrender of such Security, a new Security or Securities in the aggregate
principal amount equal to the unredeemed portion thereof will be issued;

     (e) that Securities called for redemption must be surrendered to the Paying
Agent to collect the Redemption Price;

     (f) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security or portion thereof to be redeemed, and that
(unless the Company shall default in payment of the Redemption Price) interest
thereon shall cease to accrue on and after said date;

     (g) the names and addresses of the Paying Agent and the offices or agencies
referred to in Section 1002 where such Securities are to be surrendered for
payment of the Redemption Price;

     (h) subject to Section 310, the CUSIP number, if any, relating to such
Securities; and

                                      101
<PAGE>
 
     (i) the procedures that a Holder must follow to surrender the Securities to
be redeemed.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's written request, by
the Trustee in the name and at the expense of the Company.  If the Company
elects to give notice of redemption, it shall provide the Trustee with a
certificate stating that such notice has been given in compliance with the
requirements of this Section 1105.

     The notice if mailed in the manner herein provided shall be conclusively
presumed to have been given, whether or not the Holder receives such notice.  In
any case, failure to give such notice by mail or any defect in the notice to the
Holder of any Security designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other Security.

     Section 1106.  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company or any of its Affiliates is
acting as Paying Agent, segregate and hold in trust as provided in Section 1003)
an amount of money in same day funds sufficient to pay timely the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date
or Special Payment Date) accrued interest on, all the Securities or portions
thereof which are to be redeemed on that date.  The Paying Agent shall promptly
mail or deliver to Holders of Securities so redeemed payment in an amount equal
to the Redemption Price of the Securities purchased from each such Holder.  All
money, if any, earned on funds held in trust by the Trustee or any Paying Agent
shall be remitted to the Company.  For purposes of this Section 1106, the
Company shall choose a Paying Agent which shall not be the Company.

     Section 1107.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrue
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price together with accrued and unpaid
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such on the relevant Regular Record Dates and Special
Record Dates according to the terms and the provisions of Section 309.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and premium, if any, shall, until paid,
bear interest from the Redemption Date at the rate borne by such Security.

     Section 1108.  Securities Redeemed or Purchased in Part.

     Any Security which is to be redeemed or purchased only in part shall be
surrendered to the Paying Agent at the office or agency maintained for such
purpose pursuant to Section 1002 (with, if the Company, the Security Registrar
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, the Security Registrar or the
Trustee, as the case may be, duly executed by, the Holder thereof or such
Holder's attorney duly authorized in writing), and the Company shall execute,
and the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in exchange for, the unredeemed portion of the principal of the Security so
surrendered that is not redeemed or purchased.

all Outstanding Securities hereunder, and the Trustee, upon Company Request and
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

     (a)  either

          (1) all the Securities theretofore authenticated and delivered (other
     than (i) lost, stolen or destroyed Securities which have been replaced or
     paid as provided in Section 308 or (ii) all Securities for whose payment
     (x) cash in United States dollars or (y) U.S. Government Obligations
     maturing as to principal, premium (if any) and interest in such amounts of
     money and at such times as are sufficient without consideration of any
     reinvestment of such interest, to pay principal of and interest on the
     Outstanding Securities not later than one day before the due date of any
     payment, have theretofore been deposited in trust with the Trustee or any
     Paying Agent) have been delivered to the Trustee for cancellation; or

          (2) all such Securities not theretofore delivered to the Trustee for
     cancellation (i) have become due and payable, (ii) will become due and
     payable at their Stated Maturity within one year or (iii) are to be called

violation of, or constitute a default under, this Indenture or any other

is bound.

     Notwithstanding the satisfaction and discharge hereof, (A) the obligations

and in the manner hereinafter set forth in this Article, the Indebtedness
represented by the Securities and the payment of the principal of, premium, if
any, and interest on, the Securities are hereby expressly made subordinate and
subject in right of payment as provided in this Article to the prior payment in
full of the Senior Indebtedness.

     This Article Thirteen shall constitute a continuing offer to all persons,
who, in reliance upon such provisions, become, holders of, or continue to hold
Senior Indebtedness; and such provisions are made for the benefit of the holders
of Senior Indebtedness; and such holders are made obligees hereunder and they or
each of them may enforce such provisions as provided herein.

Company, whether voluntary or involuntary, or whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshaling of assets or liabilities of the Company, then and in any
such event:

any kind or character (excluding securities of the Company as reorganized or
readjusted or securities of the Company or any other corporation provided for by
a plan of reorganization or readjustment the payment of which are subordinated
in right of payment to all Senior Indebtedness, that may be outstanding, at
least to the extent as, or to a greater extent than, the Securities are so
subordinated as provided in this Article ("Permitted Junior Securities")) on

<PAGE>
 
     (2) any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities (excluding Permitted Junior
Securities), by set-off or otherwise, to which the Holders or the Trustee would
be entitled but for the provisions of this Article shall be paid by the
liquidating trustee or agent or other person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise, directly to the holders of Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, ratably according to the aggregate amounts remaining
unpaid on account of the Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full of all Senior Indebtedness remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness; and

     (3) if, notwithstanding the foregoing provisions of this Section, the
Trustee or the Holder of any Security, shall have received any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (excluding Permitted Junior Securities), in respect of
principal, premium, if any, and interest on the Securities or on account of the
purchase, redemption, defeasance or other acquisition of, or in respect of, the
Securities (other than amounts previously set aside with the Trustee, or
payments previously made, in either case, pursuant to Sections 402 and 403 of
this Indenture) before all Senior Indebtedness is paid in full, then and in such
event such payment or distribution (excluding Permitted Junior Securities) shall
be paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other person making payments
or distributions of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness; and

into, another person or the liquidation or dissolution of the Company following

properties and assets substantially as an entirety to another person upon the
terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation, reorganization, assignment for the benefit
of creditors or marshaling of assets and liabilities of the Company for the
purposes of this Section if the person formed by such consolidation or the
surviving entity of such merger or the person which acquires by sale,
assignment, conveyance, transfer, lease or other disposal of such properties and
assets substantially as an entirety, as the case may be, shall, as a part of
such consolidation, merger, sale, assignment, conveyance, transfer, lease or
other disposal, agree to be bound by the subordination provisions contained in

the continuance of any default in the payment of any principal of, premium, if
any, or interest on, or unreimbursed amounts under drawn letters of credit or
fees relating to letters of credit constituting, any Designated Senior
Indebtedness beyond any applicable grace period (a "Payment Default") and after
the receipt by the Trustee from a Senior Representative of any Designated Senior
Indebtedness of written notice of such default, no payment (other than amounts
previously set aside with the Trustee or payments previously made, in either
case, pursuant to Section 402 or 403 in this Indenture) or distribution of any
assets of the Company or any Subsidiary of any kind or character (excluding

respect of, the Securities unless and until such Payment Default shall have been
cured or waived or shall have

ceased to exist or the Designated Senior Indebtedness shall have been discharged
or paid in full in cash or cash equivalents, after which the Company shall
(subject to the other provisions of this Article Thirteen) resume making any and
all required payments in respect of the Securities, including any missed
payments.

     (b) Unless Section 1302 shall be applicable, (1) upon the occurrence and
during the continuance of any default other than a Payment Default with respect
to any Designated Senior Indebtedness pursuant to which the maturity thereof may
then be accelerated immediately (a "Non-payment Default") and (2) after the
receipt by the Trustee and the Company from a Senior Representative of any
Designated Senior Indebtedness of written notice of such Non-payment Default, no
payment (other than any amounts previously set aside with the Trustee, or
payments previously made, in either case, pursuant to the provisions of Sections
402 or 403 in this Indenture) or distribution of any assets of the Company of
any kind or character (excluding Permitted Junior Securities) may be made by the
Company or any Subsidiary on account of the principal of, premium, if any, or
interest on, the Securities, or on account of the purchase, redemption,
defeasance or other acquisition of, or in respect of, the Securities for the
period specified below ("Payment Blockage Period").

     (c) The Payment Blockage Period shall commence upon the receipt of notice
of the Non-payment Default by the Trustee and the Company from a Senior
Representative stating that such notice is a payment blockage notice pursuant to
this Indenture and shall end on the earliest to occur of the following events:
(i) 179 days shall have elapsed since the receipt by the Trustee of such notice,
(ii) the date, as set forth in a written notice to the Company or Trustee from a
Senior Representative initiating such Payment Blockage Period, on which such
Non-Payment Default (and all Non-payment Defaults as to which notice is given
after such Payment Blockage Period is initiated) is cured or waived or ceases to
exist (provided that no other Payment Default or Non-payment Default has
occurred or is then continuing after giving effect to such cure or waiver) or on
which such Designated Senior Indebtedness is discharged or paid in full, or
(iii) the date, set forth in a written notice to the Company or Trustee from a
Senior Representative initiating such Payment Blockage Period, on which such
Payment Blockage Period (and all Non-payment Defaults as to which notice is
given after such Payment Blockage Period is initiated) shall have been
terminated by written notice to the Company or the Trustee from the Senior
Representative initiating such Payment Blockage Period, after which, in the case
of the immediately preceding clauses (i), (ii) and (iii), the Company, subject
to the subordination provisions set forth above and the existence of another
Payment Default, shall promptly resume making any and all required payments in
respect of the Securities, including any missed payments.  Only one Payment
Blockage Period with respect to the Securities may be commenced within any 360
consecutive day period.  No Non-payment Default with respect to Designated
Senior Indebtedness that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period will be, or can be,
made the basis for the commencement of a second Payment Blockage Period, whether
or not within a period of 360 consecutive days, unless such default has been
cured or waived for a period of not less than 90 consecutive days (it being
acknowledged that any subsequent action, or any breach of any financial covenant
for a period commencing after the date of commencement of such Payment Blockage
Period, that, in either case, would give rise to a Non-payment Default pursuant
to any provision under which a Non-payment Default previously existed or was
continuing shall constitute a new Non-payment Default for this purpose; provided
that, in the case of a breach of a particular financial covenant, the Company
shall have been in compliance for at least one full 90 consecutive day period
commencing after the date of commencement of such Payment Blockage Period).  In
no event will a Payment Blockage Period extend beyond 179 days from the date of
the receipt by the Trustee of the notice, and there must be a 181 consecutive
day period in any 360-day period during which no Payment Blockage Period is in
effect.  The Company shall deliver a notice to the Trustee promptly after the
date on which any Non-payment Default is cured or waived in writing or ceases to
exist or on which the Designated Senior Indebtedness related thereto is
discharged or paid in full, and the Trustee is authorized to act in reliance on
such notice.

     (d) If, notwithstanding the foregoing, the Company shall make any payment
or distribution of any assets of the Company or any Subsidiary of any kind or
character (excluding Permitted Junior Securities) to the Trustee or the Holder
of any Security prohibited by the foregoing provisions of this Section, then and
in such event such payment shall be held in trust for the holders of Senior
Indebtedness and paid over and delivered forthwith to a Senior Representative of
the holders of the Designated Senior Indebtedness or as a court of competent
jurisdiction shall direct.

     Section 1304.  Payment Permitted if No Default.

     Nothing contained in this Article, elsewhere in this Indenture or in any of
the Securities shall prevent the Company, at any time except during the pendency
of any case, proceeding, dissolution, liquidation or other winding-up,
assignment for the benefit of creditors or other marshaling of assets and
liabilities of the Company referred to in Section 1302 or under the conditions
described in Section 1303, from making payments at any time of principal of,
premium, if any, or interest on the Securities.

     Section 1305.  Subrogation to Rights of Holders of Senior Indebtedness.

     After the payment in full of all Senior Indebtedness, the Holders of the
Securities shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any, and interest on, the Securities shall be paid in full.  For
purposes of such subrogation, no payments or distributions to the holders of
Senior Indebtedness of any cash property or securities to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article, and no payments over pursuant to the provisions of this Article to
the holders of Senior Indebtedness by Holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior
Indebtedness, and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

     Section 1306.  Provisions Solely to Define Relative Rights.

     The provisions of this Article are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional, to pay to the Holders of the
Securities the principal of, premium, if any, and interest on, the Securities as
and when the same shall become due and payable in accordance with their terms;
or (b) affect the relative rights against the Company or the Holders of the
Securities and creditors of the Company other than the holders of Senior
Indebtedness; or (c) prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness (1) in any case, proceeding, dissolution, liquidation or
other winding up, assignment for the benefit of creditors or other marshaling of
assets and liabilities of the Company referred to in Section 1302, to receive,
pursuant to and in accordance with such Section, cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder, or (2) under the
conditions specified in Section 1303, to prevent any payment prohibited by such
Section or enforce their rights pursuant to Section 1303(d).

     Section 1307.  Trustee to Effectuate Subordination.

     Each Holder of a Security by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee such Holder's attorney-in-fact for any and all
such purposes including, in the event of any dissolution, winding-up,
liquidation or reorganization of

                                      107
<PAGE>
 
the Company whether in bankruptcy, insolvency, receivership proceedings, or
otherwise, the timely filing of a claim for the unpaid balance of the
indebtedness of the Company owing to such Holder in the form required in such
proceedings and the causing of such claim to be approved.

     Section 1308.  No Waiver of Subordination Provisions.

     (a) No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder or any Senior
Representative, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
any such holder may have or be otherwise charged with.

     (b) Without limiting the generality of subsection (a) of this Section 1308,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (1) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (2) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any person liable in any manner for the collection or
payment of Senior Indebtedness; (4) exercise or refrain from exercising any
rights against the Company and any other person; and (5) sell, assign or
transfer the Senior Indebtedness to any person; provided, however, that in no
event shall any such actions limit the right of the Holders of the Securities to
take any action to accelerate the maturity of the Securities pursuant to Article
Five of this Indenture or to pursue any rights or remedies hereunder or under
applicable laws if the taking of such action does not otherwise violate the
terms of this Article.

     Section 1309.  Notice to Trustee.

     (a) The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities.  Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until a Responsible Officer of the Trustee shall have received written
notice thereof from the Company or a holder of Senior Indebtedness or from a
Senior Representative or any trustee, fiduciary or agent therefor; and, prior to
the receipt of any such written notice, the Trustee shall be entitled in all
respects to assume that no such facts exist; provided, however, that if a
Responsible Officer of the Trustee shall not have received the notice provided
for in this Section by Noon, Eastern Time, on the Business Day prior to the date
upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of, premium, if
any, or interest on any Security), then, anything herein contained to the
contrary notwithstanding but without limiting the rights and remedies of the
holders of Senior Indebtedness, a Senior Representative or any trustee,
fiduciary or agent thereof, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it after such date; nor shall the Trustee be charged with knowledge
of the curing of any such default or the elimination of the act or condition
preventing any such payment unless and until the Trustee shall have received an
Officers' Certificate to such effect.

     (b) The Trustee shall be entitled to rely on the delivery to it of a
written notice to the Trustee and the Company by a person which represents
itself as a Senior Representative or a holder of Senior

                                      108
<PAGE>
 
Indebtedness (or a trustee, fiduciary or agent there for) to establish that such
notice has been given by a Senior Representative or a holder of Senior
Indebtedness (or a trustee, fiduciary or agent therefor); provided, however,
that failure to give such notice to the Company shall not affect in any way the
ability of the Trustee to rely on such notice.  If the Trustee determines in
good faith that further evidence is required with respect to the right of any
person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article, the Trustee may request such person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness held by such person, the extent to which such person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such person pending
judicial determination as to the right of such person to receive such payment.

     Section 1310.  Reliance on Judicial Orders or Certificates.

     Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee and the Holders of the Securities shall be entitled to
rely upon any order or decree entered by any court of competent jurisdiction in
which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other person making
such payment or distribution, or a certificate of a Senior Representative
delivered to the Trustee or to the Holders of Securities for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article,
provided that the foregoing shall apply only if such court has been fully
apprised of the provisions of this Article.

     Section 1311.  Rights of Trustee as a Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.  Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 607.

     Section 1312.  Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting under this Indenture, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1311 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

     Section 1313.  No Suspension of Remedies.

     Nothing contained in this Article shall limit the right of the Trustee or
the Holders of Securities to take any action to accelerate the maturity of the
Securities pursuant to Article Five of this Indenture or to pursue any rights or
remedies hereunder or under applicable law, subject to the rights if any, under
this Article of the holders, from time to time, of Senior Indebtedness to
receive the cash, property or securities receivable from the Company or any
Subsidiary upon the exercise of such rights or remedies.

     Section 1314.  Trustee's Relation to Senior Indebtedness.

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of Senior Indebtedness shall be read into this
Article against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the Holders of Senior Indebtedness and the Trustee shall not
be liable to any holder of Senior Indebtedness if it shall in good faith
mistakenly (absent negligence or willful misconduct) pay over or deliver to
Holders, the Company or any other person moneys or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article or otherwise.


                                ARTICLE FOURTEEN

                                   GUARANTEES

     Section 1401.  Guarantors' Guarantee.

     For value received, each of the Guarantors, in accordance with this Article
Fourteen, hereby absolutely, unconditionally and irrevocably guarantees, jointly
and severally, to the Trustee and the Holders, as if the Guarantors were the
principal debtor, the punctual payment and performance when due of all Indenture
Obligations (which for purposes of this Guarantee shall also be deemed to
include all commissions, fees, charges, costs and other expenses (including
reasonable legal fees and disbursements of one counsel) arising out of or
incurred by the Trustee or the Holders in connection with the enforcement of
this Guarantee).

     Section 1402.  Continuing Guarantee; No Right of Set-Off: Independent
Obligation.

     (a) This Guarantee shall be a continuing guarantee of the payment and
performance of all Indenture Obligations and shall remain in full force and
effect until the payment in full of all of the Indenture Obligations and shall
apply to and secure any ultimate balance due or remaining unpaid to the Trustee
or the Holders; and this Guarantee shall not be considered as wholly or
partially satisfied by the payment or liquidation at any time or from time to
time of any sum of money for the time being due or remaining unpaid to the
Trustee or the Holders.  Each Guarantor, jointly and severally, covenants and
agrees to comply with all obligations, covenants, agreements and provisions
applicable to it in this Indenture including those set forth in Article Eight.
Without limiting the generality of the foregoing, each Guarantor's liability
shall extend to all amounts which constitute part of the Indenture Obligations
and would be owed by the Company under this Indenture and the Securities but for
the fact that they are unenforceable, reduced, limited, impaired, suspended or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Company.

     (b) Each Guarantor, jointly and severally, hereby guarantees that the
Indenture Obligations will be paid to the Trustee without set-off or
counterclaim or other reduction whatsoever (whether for taxes, withholding or
otherwise) in lawful currency of the United States of America.

     (c) Each Guarantor, jointly and severally, guarantees that the Indenture
Obligations shall be paid strictly in accordance with their terms regardless of
any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the holders of the Securities.

     (d) Each Guarantor's liability to pay or perform or cause the performance
of the Indenture Obligations under this Guarantee shall arise forthwith after
demand for payment or performance by the Trustee has been given to the
Guarantors in the manner prescribed in Section 106 hereof.

                                      110
<PAGE>
 
     (e) Except as provided herein, the provisions of this Article Fourteen
cover all agreements between the parties hereto relative to this Guarantee and
none of the parties shall be bound by any representation, warranty or promise
made by any person relative thereto which is not embodied herein; and it is
specifically acknowledged and agreed that this Guarantee has been delivered by
each Guarantor free of any conditions whatsoever and that no representations,
warranties or promises have been made to any Guarantor affecting its liabilities
hereunder, and that the Trustee shall not be bound by any representations,
warranties or promises now or at any time hereafter made by the Company to any
Guarantor.

     (f) This Guarantee is a guarantee of payment, performance and compliance
and not of collectibility and is in no way conditioned or contingent upon any
attempt to collect from or enforce performance or compliance by the Company or
upon any event or condition whatsoever.

     (g) The obligations of the Guarantors set forth herein constitute the full
recourse obligations of the Guarantors enforceable against them to the full
extent of all their assets and properties.

     Section 1403.  Guarantee Absolute.

     The obligations of the Guarantor hereunder are independent of the
obligations of the Company under the Securities and this Indenture and a
separate action or actions may be brought and prosecuted against any Guarantor
whether or not an action or proceeding is brought against the Company and
whether or not the Company is joined in any such action or proceeding.  The
liability of the Guarantors hereunder is irrevocable, absolute and unconditional
and (to the extent permitted by law) the liability and obligations of the
Guarantors hereunder shall not be released, discharged, mitigated, waived

Indenture or the Securities, or any agreement or instrument relating to any of
the foregoing;

Indenture Obligations, or any other amendment or waiver of, or any consent to or
departure from, this Indenture or the Securities, including any increase or
decrease in the Indenture Obligations;

     (c) the taking of security from the Company, any Guarantor or any other
person, and the release, discharge or alteration of, or other dealing with, such

Indenture Obligations and the obligations of any Guarantor hereunder;

     (e) the abstention from taking security from the Company, any Guarantor or
any other person or from perfecting, continuing to keep perfected or taking

     (j) the release or discharge of the Company or any Guarantor of the
Securities or of any person liable directly as surety or otherwise by operation

might otherwise constitute a defense available to, or discharge of, the Company
or any Guarantor; or

     (s) any modification, compromise, settlement or release by the Trustee, or
by operation of law or otherwise, of the Indenture Obligations or the liability
of the Company or any other obligor under the Securities, in whole or in part,
and any refusal of payment by the Trustee, in whole or in part, from any other

     Section 1404.  Right to Demand Full Performance.

     In the event of any demand for payment or performance by the Trustee from
any Guarantor hereunder, the Trustee or the Holders shall have the right to
demand its full claim and to receive all dividends or other payments in respect
thereof until the Indenture Obligations have been paid in full, and the
Guarantors shall continue to be jointly and severally liable hereunder for any
balance which may be owing to the Trustee or the Holders by the Company under
this Indenture and the Securities.  The retention by the Trustee or the Holders
of any security, prior to the realization by the Trustee or the Holders of its
rights to such security upon foreclosure thereon, shall not, as between the
Trustee and any Guarantor, be considered as a purchase of such security, or as
payment, satisfaction or reduction of the Indenture Obligations due to the
Trustee or the Holders by the Company or any part thereof.  Each Guarantor,
promptly after demand, will reimburse the Trustee and the Holders for all costs
and expenses of collecting such amount under, or enforcing this Guarantee,
including, without limitation, the reasonable fees and expenses of counsel.

     Section 1405.  Waivers.

     (a) Each Guarantor hereby expressly waives (to the extent permitted by law)
notice of the acceptance of this Guarantee and notice of the existence, renewal
extension or the non-performance, non-payment, or non-observance on the part of
the Company of any of the terms, covenants, conditions and provisions of this
Indenture or the Securities or any other notice whatsoever to or upon the
Company or such Guarantor with respect to the Indenture Obligations, whether by
statute, rule of law or otherwise.  Each Guarantor hereby acknowledges
communication to it of the terms of this Indenture and the Securities, and all
of the provisions therein contained and consents to and approves the same.  Each
Guarantor hereby expressly waives (to the extent permitted by law) diligence,
presentment, protest and demand for payment with respect to (i) any notice of
sale, transfer or other disposition of any right, title to or interest in the
Securities by the Holders or in this Indenture, (ii) any release of any
Guarantor from its obligations hereunder resulting from any loss by it of its
rights of subrogation hereunder and (iii) any other circumstances whatsoever
that might otherwise constitute a legal or equitable discharge, release or
defense of a guarantor or surety or that might otherwise limit recourse against
such Guarantor.

     (b) Without prejudice to any of the rights or recourses which the Trustee
or the Holders may have against the Company, each Guarantor hereby expressly
waives (to the extent permitted by law) any right to require the Trustee or the
Holders to:

          (i) enforce, assert, exercise, initiate or exhaust any rights,
     remedies or recourse against the Company, any Guarantor or any other person
     under this Indenture or otherwise;

          (ii) value, realize upon, or dispose of any security of the Company or
     any other person held by the Trustee or the Holders;

          (iii)  initiate or exhaust any other remedy which the Trustee or the
     Holders may have in law or equity; or

          (iv) mitigate the damages resulting from any default under this
     Indenture;

before requiring or becoming entitled to demand payment from such Guarantor
under this Guarantee.

     Section 1406.  The Guarantors Remain Obligated if the Company is No Longer
Obligated to Discharge Indenture Obligations.

     It is the express intention of the Trustee and the Guarantors that if for
any reason the Company has no legal existence, is or becomes under no legal
obligation to discharge the Indenture Obligations

                                      113
<PAGE>
 
owing to the Trustee or the Holders by the Company or if any of the Indenture
Obligations owing to the Company to the Trustee or the Holders becomes
irrecoverable from the Company by operation of law or for any reason whatsoever,
this Guarantee and the covenants, agreements and obligations of the Guarantors
contained in this Article Fourteen shall nevertheless be binding upon the
Guarantors, as principal debtor, until such time as all such Indenture

days after all amounts due and payable by the Company under this Indenture or
the Securities shall have been paid in full.

entitled to receive or upon which the Trustee or the Holders may have a claim.

     Section 1409.  Release of Security Interests.

     Without limiting the generality of the foregoing and except as otherwise
provided in this Indenture, each Guarantor hereby consents and agrees, to the
fullest extent permitted by applicable law, that the rights of the Trustee
hereunder, and the liability of the Guarantors hereunder, shall not be affected
by any and all releases for any purpose of any collateral, if any, from the
Liens and security interests created by any collateral document and that this
Guarantee shall continue to be effective or be reinstated, as the case may be,
if at any time any payment of any of the Indenture Obligations is rescinded or
must otherwise be returned by the Trustee upon the insolvency, bankruptcy or
reorganization of the Company or otherwise, all as though such payment had not
been made.

     Section 1410.  No Bar to Further Actions.

     Except as provided by law, no action or proceeding brought or instituted

pursuance thereof shall be a bar or defense to any further action or proceeding

                                      114

of any further default or defaults under Article Fourteen and this Guarantee or
in the payment of any of the Indenture Obligations owing by the Company.

Trustee or the Holders, any right, power, privilege or remedy under this Article
Fourteen and this Guarantee shall operate as a waiver thereof, nor shall any
single or partial exercise of any rights, power, privilege or remedy preclude

power, privileges or remedies.  The rights and remedies herein provided for are
cumulative and not exclusive of any rights or remedies provided in law or
equity.

     (a) Any provision in this Article Fourteen or elsewhere in this Indenture
allowing the Trustee to request any information or to take any action authorized
by, or on behalf of any Guarantor, shall be permissive and shall not be
obligatory on the Trustee except as the Holders may direct in accordance with
the provisions of this Indenture or where the failure of the Trustee to request
any such information or to take any such action arises from the Trustee's
negligence, bad faith or willful misconduct.

     (b) The Trustee shall not be required to inquire into the existence, powers
or capacities of the Company, any Guarantor or the officers, directors or agents
acting or purporting to act on their respective behalf.

Article Fourteen.  In addition, the Guarantee with respect to each Guarantor
shall be automatically and unconditionally released and discharged to the
extent, at such times and for such periods, as provided in Section 1018(d); and
in furtherance (but not in limitation) of the foregoing, each of the Company and
the Guarantors hereby acknowledges and agrees that in the event of any release
and discharge pursuant to Section 1018(d)(ii), such release and discharge shall
only be effective for so long as, and during such periods, that such released
and discharged Guarantor does not guarantee, or secure with a Lien on any of its
assets or properties, any Indebtedness of the Company or any other Restricted
Subsidiary (including in any manner described in Section 1018(a) or Section
1018(b)), and upon each occurrence of any such guarantee or security subsequent
to each such release and discharge pursuant to Section 1018(d)(ii), such
Guarantor's Guarantee shall be automatically revived and reinstated as if such
Guarantee had not been released and discharged and shall be in full force and
effect, without any further act by such Guarantor (although the Trustee may, at
its option, request, and if requested such Guarantor promptly shall comply with
any request, that such Guarantor shall enter

                                      115
<PAGE>
 
into an amendment to this Guarantee, reasonably satisfactory to the Trustee,
memorializing such revival and reinstatement, but the failure to request or
execute any such amendment shall not impair or delay the automatic effect of
such revived and reinstated Guarantee.

     (b) Upon the delivery by the Company to the Trustee of an Officers'
Certificate and, if requested by the Trustee, an Opinion of Counsel to the
effect that the transaction giving rise to the release of this Guarantee was
made by the Company in accordance with the provisions of this Indenture and the
Securities, the Trustee shall execute any documents reasonably required in order
to evidence the release of the Guarantors from their obligations under this
Guarantee.  If any of the Indenture Obligations are revived and reinstated after
the termination of this Guarantee, then all of the obligations of the Guarantors
under this Guarantee shall be revived and reinstated as if this Guarantee had
not been terminated until such time as the Indenture Obligations are paid in
full, and each Guarantor shall enter into an amendment to this Guarantee,
reasonably satisfactory to the Trustee, evidencing such revival and
reinstatement.

     Section 1415.  Execution of Guarantee: Additional Guarantors.

     (a) To evidence the Guarantee, each Guarantor hereby agrees to execute the
guarantee substantially in the form set forth in Section 205, to be endorsed on
each Security authenticated and delivered by the Trustee and that this Indenture
shall be executed on behalf of each Guarantor by its Chairman of the Board, its
President, its Chief Executive Officer, Chief Operating Officer or one of its
Vice Presidents, attested by its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities may be manual or
facsimile.

     (b) Any Restricted Subsidiary (other than an Exempt Foreign Subsidiary),
whether now existing or hereafter formed or acquired, that was not a Guarantor
on the date of this Indenture and thereafter becomes a Significant Subsidiary,
or any Restricted Subsidiary, whether now existing or hereafter formed or
acquired, that was not a Guarantor on the date of this Indenture and thereafter
becomes a guarantor, obligor or grantor in respect of any other Indebtedness of
the Company or any other Restricted Subsidiary, or obligor on its Indebtedness,
in each case as provided in Section 1018, shall become, or any person that was
not a Guarantor on the date of this Indenture may become, a Guarantor by
executing and delivering to the Trustee (i) a supplemental indenture in form and
substance satisfactory to the Trustee, which subjects such person to the
provisions (including the representations and warranties) of this Indenture as a
Guarantor, (ii) if as of the date of such supplemental indenture any Registrable
Securities are outstanding, an instrument in form and substance satisfactory to
the Trustee which subjects such person to the provisions of the Registration
Rights Agreement with respect to such outstanding Registrable Securities, and
(iii) an Opinion of Counsel to the effect that such supplemental indenture has
been duly authorized and executed by such person and constitutes the legal,
valid and binding obligation of such person (subject to such customary
assumptions and exceptions as may be acceptable to the Trustee in its reasonable
discretion).

     (c) If an officer whose signature is on this Indenture no longer holds that
office at the time the Trustee authenticates a Security on which this Guarantee
is endorsed, such Guarantee shall be valid nevertheless.

     Section 1416.  Guarantee Subordinate to Guarantor Senior Indebtedness.

     Each Guarantor covenants and agrees, and each Holder of a Guarantee, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the Indebtedness represented
by the Guarantees is hereby expressly made subordinate and subject in right of
payment as provided in this Article to the prior payment in full of all
Guarantor Senior Indebtedness; provided, however, that the Indebtedness
represented by this Guarantee in all respects shall rank equally with, or prior
to, all existing and future Indebtedness of such Guarantor that is expressly
subordinated to such Guarantor's Guarantor Senior Indebtedness.

                                      116
<PAGE>
 
     This Article Fourteen shall constitute a continuing offer to all persons
who, in reliance upon such provisions, become holders of, or continue to hold
Guarantor Senior Indebtedness; and such provisions are made for the benefit of
the holders of Guarantor Senior Indebtedness; and such holders are made obligees
hereunder and they or each of them may enforce such provisions.

     Section 1417.  Payment Over of Proceeds Upon Dissolution of the Guarantor,
etc.

receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to any Guarantor (or to its creditors, as such)
or to its assets, or (b) any liquidation, dissolution or other winding up of any
Guarantor, whether voluntary or involuntary, or whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshaling of assets or liabilities of any Guarantor, then and in any
such event:

     (1) the holders of Guarantor Senior Indebtedness shall be entitled to
receive payment in full of all amounts due on or in respect of all Guarantor
Senior Indebtedness before the Holders of the Securities are entitled to receive
any payment or distribution of any kind or character (excluding Securities of
any Guarantor as reorganized or readjusted or Securities of such Guarantor or
any other corporation provided for by a plan of reorganization or readjustment
the payment of which are subordinated in right of payment to all Guarantor
Senior Indebtedness that may be outstanding, at least to the same extent as, or
to a greater extent than, the Guarantees are so subordinated as provided in this
Article ("Permitted Guarantor Junior Securities")) on account of the Guarantee
of such Guarantor (other than amounts previously set aside with the Trustee, or
payments previously made, in either case, pursuant to the provisions of Sections
402 and 403 of this Indenture); and

     (2) any payment or distribution of assets of any Guarantor of any kind or
character, whether in cash, property or securities (excluding Permitted
Guarantor Junior Securities), by set-off or otherwise, to which the Holders or
the Trustee would be entitled but for the provisions of this Article shall be
paid by the liquidating trustee or agent or other person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise, directly to the holders of Guarantor Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Guarantor Senior
Indebtedness may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of the Guarantor Senior Indebtedness held or
represented by each to the extent necessary to make payment in full of all
Guarantor Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Guarantor Senior
Indebtedness; and

     (3) if, notwithstanding the foregoing provisions of this Section, the
Trustee or the Holder of any Security shall have received any payment or
distribution of assets of any Guarantor of any kind or character, whether in
cash, property or securities (excluding Permitted Guarantor Junior Securities),
in respect of the Guarantee of such Guarantor or on account of the purchase,
redemption, defeasance or other acquisition of, or in respect of, the Guarantee
of such Guarantor (other than amounts previously set aside with the Trustee, or
payments previously made, in either case pursuant to Sections 402 and 403 of
this Indenture) before all Guarantor Senior Indebtedness is paid in full, then
and in such event such payment or distribution (excluding Permitted Guarantor
Junior Securities) shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
person, making payments or distributions of assets of such Guarantor for
application to the payment of all Guarantor Senior Indebtedness remaining
unpaid, to the extent necessary to pay all Guarantor Senior Indebtedness in full
after giving effect to any concurrent payment or distribution to or for the
holders of Guarantor Senior Indebtedness; and

                                      117
<PAGE>
 
     (4) the Trustee shall execute and deliver to any Senior Representative all
such further instruments as shall be reasonably requested confirming the
subordination of the Guarantees pursuant to this Article Fourteen.

     The consolidation of any Guarantor with, or the merger of any Guarantor
with or into, another person or the liquidation or dissolution of any Guarantor
following the sale, assignment, conveyance, transfer, lease or other disposal of
its properties and assets substantially as an entirety to another person upon
the terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation, reorganization, assignment for the benefit
of creditors or marshaling of assets and liabilities of such Guarantor for the
purposes of this Section if the person formed by such consolidation or the
surviving entity of such merger or the person which acquires by sale,
assignment, conveyance, transfer, lease or other disposal of such properties and
assets substantially as an entirety, as the case may be, shall, as a part of
such consolidation, merger, sale, assignment, conveyance, transfer, lease or
other disposal, agree to be bound by the subordination provisions contained in

payment duly provided for before any payment is made by any of the Guarantors or
any person acting on behalf of any of the Guarantors in respect of the Guarantee
of such Guarantor.

     (b) No payment or distribution of any assets of any Guarantor of any kind
or character (excluding Permitted Guarantor Junior Securities) shall be made by
any Guarantor in respect of its Guarantee during the period in which Section
1417 shall be applicable, during any suspension of payments in effect under
Section 1303(a) of this Indenture or during any Payment Blockage Period in
effect under Sections 1303(b) and (c) of this Indenture.

     (c) If, notwithstanding the foregoing, any Guarantor shall make any payment
or distribution of any assets of any Guarantor of any kind or character

of its Guarantee prohibited by the foregoing provisions of this Section, then
and in such event such payment shall be held in trust for the holders of Senior
Indebtedness and paid over and delivered forthwith to the representatives of the
holders of the Guarantor Senior Indebtedness or as a court of competent
jurisdiction shall direct.

     Section 1419.  Payment Permitted by Each of the Guarantors if No Default.

     Nothing contained in this Article, elsewhere in this Indenture or in any of
the Securities shall prevent any Guarantor, at any time except during the
pendency of any case, proceeding, dissolution, liquidation or other winding-up,
assignment for the benefit of creditors or other marshaling of assets and
liabilities of such Guarantor referred to in Section 1417 or under the
conditions described in Section 1418, from making payments at any time of
principal of, premium, if any, or interest on the Securities.

     Section 1420.  Subrogation to Rights of Holders of Guarantor Senior
Indebtedness.

     After the payment in full of all Guarantor Senior Indebtedness, the Holders
of the Securities shall be subrogated to the rights of the holders of such
Guarantor Senior Indebtedness to receive payments and distributions of cash,
property and securities applicable to the Guarantor Senior Indebtedness until
the principal of, premium, if any, and interest on, the Securities shall be paid
in full.  For purposes of such

                                      118
<PAGE>
 
subrogation, no payments or distributions to the holders of Guarantor Senior
Indebtedness of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article and no payments over pursuant to the provisions of this Article to the
holders of Guarantor Senior Indebtedness by Holders of the Securities or the
Trustee, shall, as among any Guarantor, its creditors other than holders of
Guarantor Senior Indebtedness, and the Holders of the Securities, be deemed to
be a payment or distribution by such Guarantor to or on account of the Guarantor
Senior Indebtedness.

     Section 1421.  Provisions Solely to Define Relative Rights.

     The provisions of Sections 1416 through 1429 of this Indenture are intended
solely for the purpose of defining the relative rights of the Holders of the
Securities on the one hand and the holders of Guarantor Senior Indebtedness on
the other hand.  Nothing contained in this Article or elsewhere in this
Indenture or in the Securities is intended to or shall (a) impair, as among any
Guarantor, its creditors other than holders of Guarantor Senior Indebtedness and
the Holders of the Securities, the obligation of such Guarantor, which is
absolute and unconditional, to pay to the Holders of the Securities the
principal of, premium, if any, and interest on, the Securities as and when the
same shall become due and payable in accordance with their terms; or (b) affect
the relative rights against each of the Guarantors of the Holders of the
Securities and creditors of each of the Guarantors other than the holders of
Guarantor Senior Indebtedness; or (c) prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
of the holders of Guarantor Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Guarantors
referred to in Section 1417, to receive, pursuant to and in accordance with such
Section, cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder, or (2) under the conditions specified in Section 1418,
to prevent any payment prohibited by such Section or enforce their rights
pursuant to Section 1418(c).

     Section 1422.  Trustee to Effectuate Subordination.

     Each Holder of a Security by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee such Holder's attorney-in-fact for any and all
such purposes, including, in the event of any dissolution, winding-up,
liquidation or reorganization of any Guarantor whether in bankruptcy,
insolvency, receivership proceedings, or otherwise, the timely filing of a claim
for the unpaid balance of the indebtedness of any Guarantor owing to such Holder
in the form required in such proceedings and the causing of such claim to be
approved.

     Section 1423.  No Waiver of Subordination Provisions.

     (a) No right of any present or future holder of any Guarantor Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
any Guarantor or by any act or failure to act, in good faith, by any such holder
or any Senior Representative, or by any non-compliance by any Guarantor with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof any such holder may have or be otherwise charged with.

     (b) Without limiting the generality of subsection (a) of this Section 1423,
the holders of Guarantor Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Guarantor Senior Indebtedness, do any one or more of the following: (1) change
the manner, place or terms of payment or extend the time of

                                      119
<PAGE>
 
payment of, or renew or alter, Guarantor Senior Indebtedness or any instrument
evidencing the same or any agreement under which Guarantor Senior Indebtedness
is outstanding; (2) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Guarantor Senior Indebtedness; (3)
release any person liable in any manner for the collection or payment of
Guarantor Senior Indebtedness; (4) exercise or refrain from exercising any
rights against any of the Guarantors and any other person; and (5) sell, assign
or transfer the Guarantor Senior Indebtedness to any person; provided, however,
that in no event shall any such actions limit the right of the Holders of the
Securities to take any action to accelerate the maturity of the Securities
pursuant to Article Five of this Indenture or to pursue any rights or remedies
hereunder or under applicable laws if the taking of such action does not
otherwise violate the terms of this Article.

     Section 1424.  Notice to Trustee by Each of the Guarantors.

     (a) Each Guarantor shall give prompt written notice to the Trustee of any
fact known to such Guarantor which would prohibit the making of any payment to
or by the Trustee in respect of the Guarantee.  Notwithstanding the provisions
of this Article or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from any
Guarantor or a holder of Guarantor Senior Indebtedness or any trustee, fiduciary
or agent therefor; and, prior to the receipt of any such written notice, the
Trustee shall be entitled in all respects to assume that no such facts exist;
provided, however, that if the Trustee shall not have received the notice
provided for in this Section by Noon, Eastern Time, on the Business Day prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of,
premium, if any, or interest on any Security), then, anything herein contained
to the contrary notwithstanding but without limiting the rights and remedies of
the holders of Guarantor Senior Indebtedness or any trustee, fiduciary or agent
thereof, the Trustee shall have full power and authority to receive such money
and to apply the same to the purpose for which such money was received and shall
not be affected by any notice to the contrary which may be received by it after
such date; nor shall the Trustee be charged with knowledge of the curing of any
such default or the elimination of the act or condition preventing any such
payment unless and until the Trustee shall have received an Officers'
Certificate to such effect.

     (b) The Trustee shall be entitled to rely on the delivery to it of a
written notice to the Trustee and each Guarantor by a person which represents
itself as a representative of one or more holders of Guarantor Senior or a
holder of Guarantor Senior Indebtedness (or a trustee, fiduciary or agent
therefor) to establish that such notice has been given by a representative of or
a holder of Guarantor Senior Indebtedness (or a trustee, fiduciary or agent
therefor); provided, however, that failure to give such notice to the Company or
any Guarantor shall not affect in any way the ability of the Trustee to rely on
such notice.  If the Trustee determines in good faith that further evidence is
required with respect to the right of any person as a holder of Guarantor Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Guarantor Senior
Indebtedness held by such person, the extent to which such person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such person under this Article, and if such evidence is not furnished,
the Trustee may defer any payment to such person pending judicial determination
as to the right of such person to receive such payment.

     Section 1425.  Reliance on Judicial Orders or Certificates.

     Upon any payment or distribution of assets of any Guarantor referred to in
this Article, the Trustee and the Holders of the securities shall be entitled to
rely upon any order or decree entered by any court of competent jurisdiction in
which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the

                                      120
<PAGE>
 
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for
the benefit of creditors, agent or other person making such payment or
distribution, delivered to the Trustee or to the Holders of Securities for the
purpose of ascertaining the persons entitled to participate in such payment or
distribution, the holders of Guarantor Senior Indebtedness and other
indebtedness of such Guarantor, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article, provided that the foregoing shall apply only if such
court has been fully apprised of the provisions of this Article.

     Section 1426.  Rights of Trustee as a Holder of Guarantor Senior
Indebtedness; Preservation of Trustee's Rights.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Guarantor Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Guarantor Senior Indebtedness, and nothing in this Indenture shall deprive the
Trustee of any of its rights as such holder.  Nothing in this Article shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
607.

     Section 1427.  Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting under this Indenture, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1426 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

     Section 1428.  No Suspension of Remedies.

     Nothing contained in this Article shall limit the right of the Trustee or
the Holders of Securities to take any action to accelerate the maturity of the
Securities pursuant to Article Five of this Indenture or to pursue any rights or
remedies hereunder or under applicable law, subject to the rights, if any, under
this Article of the holders, from time to time, of Guarantor Senior Indebtedness
to receive the cash, property or securities receivable from any Guarantor upon
the exercise of such rights or remedies.

     Section 1429.  Trustee's Relation to Guarantor Senior Indebtedness.

     With respect to the holders of Guarantor Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article, and no implied covenants or
obligations with respect to the holders of Guarantor Senior Indebtedness shall
be read into this Article against the Trustee.  The Trustee shall not be deemed
to owe any fiduciary duty to the holders of Guarantor Senior Indebtedness and
the Trustee shall not be liable to any holder of Guarantor Senior Indebtedness
if it shall in good faith mistakenly (absent negligence or willful misconduct)
pay over or deliver to Holders, the Company or any other person moneys or assets
to which any holder of Guarantor Senior Indebtedness shall be entitled by virtue
of this Article or otherwise.

          2.   Registration Under the 1933 Act.

          2.1  Exchange Offer.  The Company and the Guarantors shall, for the
benefit of the Holders, at the Company's cost, (A) prepare and, as soon as
practicable but not later than 45 days following the Closing Date, file with the
SEC an Exchange Offer Registration Statement on an appropriate form under the
1933 Act with respect to a proposed Exchange Offer and the issuance and delivery
to the Holders, in exchange for the Registrable Securities (other than Unsold
Securities and Private Exchange Securities), of a like principal amount of
Exchange Securities, (B) use its best efforts to cause the Exchange Offer
Registration Statement to be declared effective under the

                                       5
<PAGE>
 
1933 Act within 105 days of the Closing Date, (C) use their best efforts to keep
the Exchange Offer Registration Statement effective until the closing of the
Exchange Offer and (D) use their best efforts to cause the Exchange Offer to be
consummated not later than 135 days following the Closing Date.  The Exchange
Securities will be issued under the Indenture.  Upon the effectiveness of the
Exchange Offer Registration Statement, the Company and the Guarantors shall
promptly commence the Exchange Offer, it being the objective of such Exchange
Offer to enable each Holder eligible and electing to exchange Registrable
Securities (other than Unsold Securities and Private Exchange Securities) for
Exchange Securities (assuming that such Holder (a) is not an affiliate of the
Company within the meaning of Rule 405 promulgated under the 1933 Act, (b) is
not a broker-dealer tendering Registrable Securities acquired directly from the
Company for its own account, (c) acquired the Exchange Securities in the
ordinary course of such Holder's business and (d) has no arrangements or
understandings with any Person to participate in the Exchange Offer for the
purpose of distributing the Exchange Securities) to transfer such Exchange
Securities from and after their receipt without any limitations or restrictions
under the 1933 Act and under state securities or blue sky laws.

          In connection with the Exchange Offer, the Company and the Guarantors
shall:

               (a) mail as promptly as practicable to each Holder a copy of the
Prospectus forming part of the Exchange Offer Registration Statement, together
with an appropriate letter of transmittal and related documents;

               (b) keep the Exchange Offer open for acceptance for a period of
not less than 30 calendar days after the date notice thereof is mailed to the
Holders (or longer if required by applicable law) (such period referred to
herein as the "Exchange Period");

               (c) utilize the services of the Depositary for the Exchange
Offer;

               (d) permit Holders to withdraw tendered Registrable Securities at
any time prior to 5:00 p.m. (Eastern Time), on the last business day of the
Exchange Period, by sending to the institution specified in the notice, a
telegram, telex, facsimile transmission or letter setting forth the name of such
Holder, the principal amount of Registrable Securities delivered for exchange,
and a statement that such Holder is withdrawing such Holder's election to have
such Securities exchanged;

               (e) notify each Holder that any Registrable Security not tendered
will remain outstanding and continue to accrue interest, but will not retain any
rights under this Agreement (except in the case of the Initial Purchasers and
Participating Broker-Dealers as provided herein); and

               (f) otherwise comply in all respects with all applicable laws
relating to the Exchange Offer.

                                       6
<PAGE>
 
          If, prior to consummation of the Exchange Offer, the Initial
Purchasers hold any Securities acquired by them and having the status of an
unsold allotment in the initial distribution ("Unsold Securities"), the Company
and the Guarantors upon the request of any Initial Purchaser shall,
simultaneously with the delivery of the Exchange Securities in the Exchange
Offer, issue and deliver to such Initial Purchaser in exchange (the "Private
Exchange") for the Securities held by such Initial Purchaser, a like principal
amount of debt securities of the Company, guaranteed by the Guarantors on the
same basis as the Unsold Securities, that are identical (except that such
securities shall bear appropriate transfer restrictions) to the Exchange
Securities (the "Private Exchange Securities").

          The Exchange Securities and the Private Exchange Securities shall be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture and which, in either case, has been qualified under
the TIA, or is exempt from such qualification and shall provide that the
Exchange Securities shall not be subject to the transfer restrictions set forth
in the Indenture but that the Private Exchange Securities shall be subject to
such transfer restrictions.  The Indenture or such indenture shall provide that
the Exchange Securities, the Private Exchange Securities and the Securities
shall vote and consent together on all matters as one class and that none of the
Exchange Securities, the Private Exchange Securities or the Securities will have
the right to vote or consent as a separate class on any matter.  The Private
Exchange Securities shall be of the same series as, and the Company and the
Guarantors shall use all commercially reasonable efforts to have the Private
Exchange Securities bear the same CUSIP number as, the Exchange Securities.
Neither the Company nor any of the Guarantors shall have any liability under
this Agreement solely as a result of such Private Exchange Securities not
bearing the same CUSIP number as the Exchange Securities.

          As soon as practicable after the close of the Exchange Offer and/or
the Private Exchange, as the case may be, the Company and the Guarantors shall:

               (i)   accept for exchange all Registrable Securities (other than
          Unsold Securities and Private Exchange Securities) duly tendered and
          not validly withdrawn pursuant to the Exchange Offer in accordance
          with the terms of the Exchange Offer Registration Statement and the
          letter of transmittal which shall be an exhibit thereto;

               (ii)  accept for exchange all Securities properly tendered
          pursuant to the Private Exchange;

               (iii) deliver, or cause to be delivered, to the Trustee for
          cancellation all Registrable Securities so accepted for exchange; and

               (iv)  cause the Trustee promptly to authenticate and deliver
          Exchange Securities or Private Exchange Securities, as the case may
          be, to each Holder of Registrable Securities so accepted for exchange
          in a

                                       7
<PAGE>
 
          principal amount equal to the principal amount of the Registrable
          Securities of such Holder so accepted for exchange.

          Interest on each Exchange Security and Private Exchange Security will
accrue from the last date on which interest was paid on the Registrable
Securities surrendered in exchange therefor or, if no interest has been paid on
the Registrable Securities, from the date of original issuance.  The Exchange
Offer and the Private Exchange shall not be subject to any conditions, other
than (i) that the Exchange Offer or the Private Exchange, or the making of any
exchange by a Holder, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) the due tendering of Registrable
Securities in accordance with the Exchange Offer and the Private Exchange, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that all Exchange Securities to be received by it shall be
acquired in the ordinary course of its business and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding
with any person to participate in the distribution (within the meaning of the
1933 Act) of the Exchange Securities and shall have made such other
representations as may be reasonably necessary under applicable SEC rules,
regulations or interpretations to render the use of Form S-4 or other
appropriate form under the 1933 Act available and (iv) that no action or
proceeding shall have been instituted or threatened in any court or by or before
any governmental agency with respect to the Exchange Offer or the Private
Exchange which, in the Company's and the Guarantors' judgment, would reasonably
be expected to impair the ability of the Company and the Guarantors to proceed
with the Exchange Offer or the Private Exchange.  The Company and the Guarantors
shall inform the Initial Purchasers of the names and addresses of the Holders to
whom the Exchange Offer is made, and the Initial Purchasers shall have the right
to contact such Holders and otherwise facilitate the tender of Registrable
Securities in the Exchange Offer.

          2.2  Shelf Registration.  (i) If, because of any changes in law, SEC
rules or regulations or applicable interpretations thereof by the staff of the
SEC, the Company and the Guarantors are not permitted to effect the Exchange
Offer as contemplated by Section 2.1, (ii) if for any other reason the Exchange
Offer Registration Statement is not declared effective within 105 days following
the original issue of the Registrable Securities or the Exchange Offer is not
consummated within 135 days after the original issue of the Registrable
Securities or (iii) if a Holder is not permitted to participate in the Exchange
Offer or elects to participate in the Exchange Offer and does not receive fully
tradeable Exchange Securities pursuant to the Exchange Offer, then in case of
each of clauses (i) through (iii) the Company and the Guarantors shall, whether
or not the Exchange Offer has been consummated, at their cost:

               (a) As promptly as practicable, file with the SEC, and thereafter
          shall use their best efforts to cause to be declared effective as
          promptly as practicable, but no later than 135 days after the original
          issue of the Registrable Securities, a Shelf Registration Statement
          relating to the offer

                                       8
<PAGE>
 
          and sale of the Registrable Securities by the Holders from time to
          time in accordance with the methods of distribution elected by the
          Majority Holders participating in the Shelf Registration and set forth
          in such Shelf Registration Statement.

               (b) Use their best efforts to keep the Shelf Registration
          Statement continuously effective to permit the Prospectus forming part
          thereof to be usable by Holders for a period of two years from the
          date the Shelf Registration Statement is declared effective by the
          SEC, or for such shorter period that will terminate when all
          Registrable Securities covered by the Shelf Registration Statement
          have been sold pursuant to the Shelf Registration Statement or cease
          to be outstanding or otherwise to be Registrable Securities (the
          "Effectiveness Period"); provided, however, that the Effectiveness
          Period in respect of the Shelf Registration Statement shall be
          extended to the extent required to permit dealers to comply with the
          applicable prospectus delivery requirements of Rule 174 promulgated
          under the 1933 Act and as otherwise provided herein.

               (c) Notwithstanding any other provisions hereof, use their best
          efforts to ensure that (i) any Shelf Registration Statement and any
          amendment thereto and any Prospectus forming part thereof and any
          supplement thereto complies in all material respects with the 1933 Act
          and the rules and regulations thereunder, (ii) any Shelf Registration
          Statement and any amendment thereto does not, when it becomes
          effective, contain an untrue statement of a material fact or omit to
          state a material fact required to be stated therein or necessary to
          make the statements therein not misleading and (iii) any Prospectus
          forming part of any Shelf Registration Statement, and any supplement
          to such Prospectus (as amended or supplemented from time to time),
          does not include an untrue statement of a material fact or omit to
          state a material fact necessary in order to make the statements, in
          light of the circumstances under which they were made, not misleading.

          The Company and the Guarantors shall not permit any securities other
than Registrable Securities to be included in the Shelf Registration Statement.
The Company and the Guarantors further agree, if necessary, to supplement or
amend the Shelf Registration Statement, as required by Section 3(b), and to
furnish to the Holders of Registrable Securities copies of any such supplement
or amendment promptly after its being used or filed with the SEC; provided,
however, that no Holder shall be entitled to have its Registrable Securities
covered by the Shelf Registration Statement unless such Holder agrees in writing
to be bound by the terms and provisions of this Agreement.

          2.3  Expenses.  The Company and the Guarantors shall pay all
Registration Expenses in connection with the registration pursuant to Section
2.1 or 2.2.  Each Holder shall pay all underwriting discounts and commissions
and transfer

                                       9
<PAGE>
 
taxes, if any, relating to the sale or disposition of such Holder's Registrable
Securities pursuant to the Shelf Registration Statement and the fees of any
separate counsel retained by such Holder.

          2.4. Effectiveness.  (a) The Company and the Guarantors will be deemed
not to have used their best efforts to cause the Exchange Offer Registration
Statement or the Shelf Registration Statement, as the case may be, to become, or
to remain, effective during the requisite period if the Company or any of the
Guarantors voluntarily takes any action that would, or omits to take any action
which omission would, result in any such Registration Statement not being
declared effective or in the Holders of Registrable Securities covered thereby
not being able to exchange or offer and sell such Registrable Securities during
that period as and to the extent contemplated hereby, unless such action is
required by applicable law.

          (b)  An Exchange Offer Registration Statement pursuant to Section 2.1
or a Shelf Registration Statement pursuant to Section 2.2 will not be deemed to
have become effective unless it has been declared effective by the SEC;
provided, however, that if, after it has been declared effective, the offering
of Registrable Securities pursuant to an Exchange Offer Registration Statement
or a Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Registration Statement will be deemed not to have become
effective during the period of such interference, until the offering of
Registrable Securities pursuant to such Registration Statement may legally
resume.

          2.5  Additional Interest.  The Indenture executed in connection with
the Securities will provide that in the event that either (a) the Exchange Offer
Registration Statement is not filed with the SEC on or prior to the 45th
calendar day following the date of original issue of the Securities, (b) the
Exchange Offer Registration Statement is not declared effective on or prior to
the 105th calendar day following the date of original issue of the Securities or
(c) with respect to any Registrable Securities (other than Unsold Securities and
Private Exchange Securities) the Exchange Offer with respect to any such
Registrable Securities is not consummated or a Shelf Registration Statement is
not declared effective, in either case, on or prior to the 135th calendar day
following the date of original issue of the Securities (each such event referred
to in clauses (a) through (c) above, a "Registration Default"), the interest
rate borne by the Securities shall be increased ("Additional Interest") by one-
quarter of one percent per annum upon the occurrence of each Registration
Default, which rate (as increased as aforesaid) will increase by one quarter of
one percent each 90-day period that such Additional Interest continues to accrue
under any such circumstance, provided that the maximum aggregate increase in the
interest rate will in no event exceed one percent per annum including any
increases pursuant to the next paragraph.  Following the cure of all
Registration Defaults the accrual of Additional Interest will cease and the
interest rate will revert to the original rate.

                                       10
<PAGE>
 
          If the Shelf Registration Statement is unusable by the Holders for any
reason, and the aggregate number of days in any consecutive twelve-month period
for which the Shelf Registration Statement shall not be usable exceeds 30 days
in the aggregate, then the interest rate borne by the Securities and the Private
Exchange Securities held by such Holders will be increased by 0.25% per annum of
the principal amount of the Securities and the Private Exchange Securities for
the first 90-day period (or portion thereof) beginning on the 31st such date
that such Shelf Registration Statement ceases to be usable, which rate shall be
increased by an additional 0.25% per annum of the principal amount of the
Securities and the Private Exchange Securities at the beginning of each
subsequent 90-day period, provided that the maximum aggregate increase in the
interest rate will in no event exceed one percent per annum including any
increases effected pursuant to the provisions of the previous paragraph.  Any
amounts payable under this paragraph shall also be deemed "Additional Interest"
for purposes of this Agreement.  Upon the Shelf Registration Statement once
again becoming usable, the interest rate borne by the Securities and the Private
Exchange Securities will be reduced to the original interest rate if the Company
is otherwise in compliance with this Agreement at such time.  Additional
Interest shall be computed based on the actual number of days elapsed in each
90-day period in which the Shelf Registration Statement is unusable.

          The Company and the Guarantors shall notify the Trustee within three
business days after each and every date on which an event occurs in respect of
which Additional Interest is required to be paid (an "Event Date").  Additional
Interest shall be paid by depositing with the Trustee, in trust, for the benefit
of the Holders of Registrable Securities, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due.  The Additional Interest due shall be payable on
each interest payment date to the record Holder of Securities entitled to
receive the interest payment to be paid on such date as set forth in the
Indenture.  Each obligation to pay Additional Interest shall be deemed to accrue
from and including the day following the applicable Event Date.

          3.   Registration Procedures.

          In connection with the obligations of the Company and the Guarantors
with respect to Registration Statements pursuant to Sections 2.1 and 2.2, the

reasonably request, including financial statements and schedules and, if the
Holder so requests, all exhibits to facilitate the public sale or other
disposition of the Registrable Securities; and (iii) subject to the third from
last paragraph of this Section 3, hereby consent to the use of the Prospectus or
any amendment or supplement thereto by each of the selling Holders of
Registrable Securities in connection with the offering and sale of the
Registrable Securities covered by the Prospectus or any amendment or supplement
thereto;

          (d) use their best efforts to register or qualify the Registrable
Securities under all applicable state securities or "blue sky" laws of such
jurisdictions as any Holder of Registrable Securities covered by a Registration
Statement and each underwriter of an underwritten offering of Registrable
Securities shall reasonably request by the time the applicable Registration
Statement is declared effective by the SEC, and do any and all other acts and
things which may be reasonably necessary or advisable to enable each such Holder
and underwriter to consummate the disposition in each such jurisdiction of such
Registrable Securities owned by such Holder; provided, however, that none of the
Company or the Guarantors shall be required to (i) qualify as a foreign
corporation or as a dealer in securities in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d) or (ii) take any
action which would subject it to general service of process or taxation in any
such jurisdiction where it is not then so subject;

Shelf Registration or any Participating Broker-Dealer who has notified the
Company and the Guarantors that it is utilizing the Exchange Offer Registration
Statement as provided in Section 3(f) and, if requested by such Holder or
Participating Broker-Dealer, confirm such advice in writing promptly (i) when a
Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of any request by the
SEC or any state securities authority for post-effective amendments and
supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (iii) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation of
any proceedings for that purpose, (iv) in the case of a Shelf Registration, if,
between the effective date of a Registration Statement and the closing of any
sale of Registrable Securities covered thereby, the representations and
warranties of the Company and the Guarantors contained in any underwriting
agreement, securities sales agreement or other similar agreement, if any,
relating to the offering cease to be true and correct in all material respects,
(v) of the happening of any event or the discovery of any facts during the
period a Shelf Registration Statement is effective which makes any statement
made in such Registration Statement or the related Prospectus untrue in any
material respect or which requires the making of any changes in such
Registration Statement or Prospectus in order to make the statements therein not
misleading, (vi) of the receipt by the Company and the Guarantors of any

Distribution" which section shall be reasonably acceptable to the Initial
Purchasers, and which shall contain a summary statement of the positions taken
or policies made by the staff of the SEC with respect to the potential
"underwriter" status of any broker-dealer that holds Registrable Securities
acquired for its own account as a result of market-making activities or other
trading activities and that will be the beneficial owner (as defined in Rule
l3d-3 promulgated under the 1934 Act) of Exchange Securities to be received by
such broker-dealer in the Exchange Offer, whether such positions or policies
have been publicly disseminated by the staff of the SEC or such positions or
policies, in the reasonable judgment of the Initial Purchasers and their
counsel, represent the prevailing views of the staff of the SEC, including a
statement that any such broker-dealer who receives Exchange Securities for
Registrable Securities pursuant to the Exchange Offer may be deemed a statutory
underwriter and must deliver a prospectus meeting the requirements of the 1933
Act in connection with any resale of such Exchange Securities, (ii) furnish to
each Participating Broker-Dealer who has delivered to the Company the notice
referred to in Section 3(e), without charge, as many copies of each Prospectus

prospectus, and any amendment or supplement thereto, as such

                                       13
<PAGE>
 
Participating Broker-Dealer may reasonably request, (iii) subject to the third
from last paragraph of this Section 3, hereby consent to the use of the
Prospectus forming part of the Exchange Offer Registration Statement or any

delivery requirements of the SEC, including all Participating Broker-Dealers, in

          is not engaged in, and does not intend to engage in, a distribution of
          the Exchange Securities.  If the exchange offeree is a broker-dealer
          holding Registrable Securities acquired for its own account as a
          result of market-making activities or other trading activities, it
          will deliver a prospectus meeting the requirements of the 1933 Act in
          connection with any resale of Exchange Securities received in respect
          of such Registrable Securities pursuant to the Exchange Offer;" and

(y) a statement to the effect that by a broker-dealer making the acknowledgment
described in clause (x) and by delivering a Prospectus in connection with the

               (B) in the case of any Exchange Offer Registration Statement, the
Company and the Guarantors agree to deliver to the Initial Purchasers on behalf

certificates substantially in the form customarily delivered in a public
offering of debt securities and (iii) a comfort letter or comfort letters in
customary form to the extent permitted by Statement on Auditing Standards No. 72

letter is not permitted, an agreed upon procedures letter in customary form)
from the Company's independent certified public accountants (and, if necessary,
any other independent certified public accountants of any subsidiary of the
Company or of any business acquired by the Company for which financial
statements are, or are required to be, included in the Registration Statement)

          (g) (i) in the case of an Exchange Offer, furnish counsel for the
Initial Purchasers and (ii) in the case of a Shelf Registration, furnish counsel

other request by the SEC or any state securities authority for amendments or
supplements to a Registration Statement and Prospectus or for additional
information;

          (h) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest
possible moment;

          (i) in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities, and each underwriter, if any, without charge, at least
one conformed copy of each Registration Statement and any post-effective
amendment thereto, including financial statements and schedules (without
documents incorporated therein by reference and all exhibits thereto, unless
requested);

          (j) in the case of a Shelf Registration, cooperate with the selling
Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends; and enable such Registrable Securities to be in
such denominations (consistent with the provisions of the Indenture) and
registered in such names as the selling Holders or the underwriters, if any, may
reasonably request at least one business day prior to the closing of any sale of
Registrable Securities;

          (k) in the case of a Shelf Registration, upon the occurrence of any
event or the discovery of any facts, each as contemplated by Sections 3(e)(v)
and 3(e)(vi), as promptly as practicable after the occurrence of such an event,
use their best efforts to prepare a supplement or post-effective amendment to
the Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Securities or
Participating Broker-Dealers, such Prospectus will not contain at the time of
such delivery any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading or will remain so
qualified.  The Company agrees to notify each Holder to suspend use of the
Prospectus as promptly as practicable after the occurrence of such an event, and
each Holder hereby agrees to suspend use of the Prospectus until the Company and
the Guarantors have amended or supplemented the Prospectus to correct such
misstatement or omission.  At such time as such public disclosure is otherwise
made or the Company determines that such disclosure is not necessary, in each
case to correct any misstatement of a material fact or to include any omitted
material fact, the Company agrees promptly to notify each Holder of such
determination and to furnish each Holder such number of copies of the Prospectus
as amended or supplemented, as such Holder may reasonably request;

          (l) in the case of a Shelf Registration, a reasonable time prior to
the filing of any Registration Statement, any Prospectus, any amendment to a
Registration Statement or amendment or supplement to a Prospectus or any
document which is to be incorporated by reference into a Registration Statement
or a Prospectus after initial filing of a Registration Statement, provide copies
of such document to the Initial

                                       15
<PAGE>
 
Purchasers on behalf of such Holders; and make representatives of the Company
and the Guarantors as shall be reasonably requested by the Holders of
Registrable Securities, or the Initial Purchasers on behalf of such Holders,
available for discussion of such document;

          (m) obtain a CUSIP number for all Exchange Securities or Registrable
Securities, as the case may be, not later than the effective date of a
Registration Statement, and provide the Trustee with printed certificates for
the Exchange Securities or the Registrable Securities, as the case may be, in a
form eligible for deposit with the Depositary;

          (n) (i) cause the Indenture to be qualified under the TIA in
connection with the registration of the Exchange Securities or Registrable
Securities, as the case may be, (ii) cooperate with the Trustee and the Holders
to effect such changes to the Indenture as may be required for the Indenture to
be so qualified in accordance with the terms of the TIA and (iii) execute, and
use their best efforts to cause the Trustee to execute, all documents as may be
required to effect such changes, and all other forms and documents required to
be filed with the SEC to enable the Indenture to be so qualified in a timely
manner;

          (o) in the case of a Shelf Registration, enter into agreements
(including underwriting agreements) and take all other customary and appropriate
actions to expedite or facilitate the disposition of such Registrable Securities
and in such connection whether or not an underwriting agreement is entered into
and whether or not the registration is an underwritten registration:

               (i)   make such representations and warranties to the Holders of
          such Registrable Securities and the underwriters, if any, in form,
          substance and scope as are customarily made by issuers to underwriters
          in similar underwritten offerings as may be reasonably requested by
          them;

               (ii)  obtain opinions of counsel to the Company and the
          Guarantors and updates thereof (which counsel and opinions (in form,
          scope and substance) shall be reasonably satisfactory to the managing
          underwriters, if any, and the holders of a majority in principal
          amount of the Registrable Securities being sold) addressed to each
          selling Holder and the underwriters, if any, covering the matters
          customarily covered in opinions requested in sales of securities or
          underwritten offerings and such other matters as may be reasonably
          requested by such Holders and underwriters;

               (iii) obtain "cold comfort" letters and updates thereof from the
          Company's and the Guarantors' independent certified public accountants
          (and, if necessary, any other independent certified public accountants
          of any subsidiary of the Company or of any business acquired by the
          Company for which financial statements are, or are required to be,

          included in the Registration Statement) addressed to the underwriters,
          if any, and use reasonable efforts to have such letters addressed to
          the selling Holders of Registrable Securities (to the extent
          consistent with Statement on Auditing Standards No. 72 of the American
          Institute of Certified Public Accounts), such letters to be in
          customary form and covering matters of the type customarily covered in
          "cold comfort" letters to underwriters in connection with similar
          underwritten offerings;

               (iv)  enter into a securities sales agreement with the Holders
          and an agent of the Holders providing for, among other things, the
          appointment of such agent for the selling Holders for the purpose of
          soliciting purchases of Registrable Securities, which agreement shall
          be in form, substance and scope customary for similar offerings;

               (v)   if an underwriting agreement is entered into, cause the
          same to set forth indemnification provisions and procedures
          substantially equivalent to the indemnification provisions and
          procedures set forth in Section 4 with respect to the underwriters and
          all other parties to be indemnified pursuant to said Section or, at
          the request of any underwriters, in the form customarily provided to
          such underwriters in similar types of transactions; and

               (vi)  deliver such documents and certificates as may be
          reasonably requested and as are customarily delivered in similar
          offerings to the Holders of a majority in principal amount of the
          Registrable Securities being sold and the managing underwriters, if
          any.

The above shall be done at (i) the effectiveness of such Registration Statement
(and each post-effective amendment thereto) and (ii) each closing under any
underwriting or similar agreement as and to the extent required thereunder.  In
the case of any underwritten offering, the Company and the Guarantors shall
provide written notice of the Holders of all Registrable Securities entitled to
have its Registrable Securities covered by the Shelf Registration Statement of
such underwritten offering at least 30 days prior to the filing of a prospectus
supplement for such underwritten offering.  Such notice shall (x) offer each
such Holder the right to participate in such underwritten offering, (y) specify
a date, which shall be no earlier than 10 days following the date of such
notice, by which such Holder must inform the Company of its intent to
participate in such underwritten offering and (z) include the instructions such
Holder must follow to participate in such underwritten offering;

          (p) in the case of a Shelf Registration or if a Prospectus is required
to be delivered by any Participating Broker-Dealer, make available for
inspection by representatives of the Holders of the Registrable Securities, any
underwriters participating in any disposition pursuant to a Shelf Registration
Statement, any Participating Broker-Dealer and any counsel or accountant
retained by any of the foregoing, all financial and other records, pertinent
corporate documents and properties

                                       17
<PAGE>
 
of the Company and the Guarantors reasonably requested by any such persons, and
cause the respective officers, directors, employees, and any other agents of the
Company and the Guarantors to supply all information reasonably requested by any
such representative, underwriter, special counsel or accountant in connection
with a Registration Statement, and make such representatives of the Company and
the Guarantors available for discussion of such documents as shall be reasonably
requested by the Initial Purchasers; provided, however, that such Persons shall
first agree in writing with the Company and the Guarantors that any information
that is reasonably and in good faith designated by the Company and the
Guarantors in writing as confidential at the time of delivery of such
information shall be kept confidential by such persons, unless (i) disclosure of
such information is required by court or administrative order or is necessary to
respond to inquiries of regulatory authorities, (ii) disclosure of such
information is required by law (including any disclosure requirements pursuant
to federal securities laws in connection with the filing of such Shelf
Registration Statement or use of any Prospectus) or legal process, (iii) such
information becomes generally available to the public other than as a result of
a disclosure or failure to safeguard such information by such Person or (iv)
such information become available to such Person from a source other than the
Company and its subsidiaries and such source is not bound by a confidentiality
agreement.

          (q)  (i)   in the case of an Exchange Offer Registration Statement, a
reasonable time prior to the filing of any Exchange Offer Registration
Statement, any Prospectus forming a part thereof, any amendment to an Exchange
Offer Registration Statement or amendment or supplement to such Prospectus,
provide copies of such document to the Initial Purchasers and to counsel to the
Holders of Registrable Securities and make such changes in any such document
prior to the filing thereof as the Initial Purchasers or counsel to the Holders
of Registrable Securities may reasonably request and, except as otherwise
required by applicable law, not file any such document in a form to which the
Initial Purchasers on behalf of the Holders of Registrable Securities and
counsel to the Holders of Registrable Securities shall not have previously been
advised and furnished a copy of or to which the Initial Purchasers on behalf of
the Holders of Registrable Securities or counsel to the Holders of Registrable
Securities shall reasonably object on or prior to the later of five business
days after receipt thereof or three business days prior to filing thereof, and
make the representatives of the Company and the Guarantors available for
discussion of such documents as shall be reasonably requested by the Initial
Purchasers; and

               (ii)  in the case of a Shelf Registration, a reasonable time
prior to filing any Shelf Registration Statement, any Prospectus forming a part
thereof, any amendment to such Shelf Registration Statement or amendment or
supplement to such Prospectus, provide copies of such document to the Holders of
Registrable Securities, to the Initial Purchasers, to counsel for the Holders
and to the underwriter or underwriters of an underwritten offering of
Registrable Securities, if any, make such changes in any such document prior to
the filing thereof as the Initial Purchasers, the counsel to the Holders or the
underwriter or underwriters reasonably request and not file any such document in
a form to which the Majority Holders, the Initial Purchasers

                                       18
<PAGE>
 
on behalf of the Holders of Registrable Securities, counsel for the Holders of
Registrable Securities or any underwriter shall not have previously been advised
and furnished a copy of or to which the Majority Holders, the Initial Purchasers
of behalf of the Holders of Registrable Securities, counsel to the Holders of
Registrable Securities or any underwriter shall reasonably object on or prior to
the later of five business days after receipt thereof or three business days
prior to filing thereof, and make the representatives of the Company and the
Guarantors available for discussion of such document as shall be reasonably
requested by the Holders of Registrable Securities, the Initial Purchasers on
behalf of such Holders, counsel for the Holders of Registrable Securities or any
underwriter.

          (r) in the case of a Shelf Registration, use their best efforts to
cause all Registrable Securities to be listed on any securities exchange on
which similar debt securities issued by the Company are then listed if requested
by the Majority Holders, or if requested by the underwriter or underwriters of
an underwritten offering of Registrable Securities, if any;

          (s) in the case of a Shelf Registration, use their best efforts to
cause the Registrable Securities to be rated by the appropriate rating agencies,
if so requested by the Majority Holders, or if requested by the underwriter or
underwriters of an underwritten offering of Registrable Securities, if any;

          (t) otherwise comply with all applicable rules and regulations of the
SEC and make available to their security holders, as soon as reasonably
practicable, an earnings statement covering at least 12 months which shall
satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 promulgated
thereunder;

          (u) cooperate and assist in any filings required to be made with the
NASD and, in the case of a Shelf Registration, in the performance of any due
diligence investigation by any underwriter and its counsel (including any
"qualified independent underwriter" that is required to be retained in
accordance with the rules and regulations of the NASD); and

          (v) upon consummation of an Exchange Offer, obtain (i) a customary
opinion of counsel to the Company and the Guarantors addressed to the Trustee
for the benefit of all Holders of Registrable Securities participating in the
Exchange Offer or Private Exchange, and which includes an opinion that (A) each
of the Company and the Guarantors has duly authorized, executed and delivered
the applicable Exchange Securities, Private Exchange Securities and the related
indenture and (B) each of the applicable Exchange Securities, Private Exchange
Securities and related indenture constitute legal, valid and binding obligations
of the Company and the Guarantors, enforceable against the Company and the
Guarantors in accordance with its respective terms (with customary exceptions)
and (ii) an officers' certificate containing certifications substantially
similar to those set forth in Section 5(c) of the Purchase Agreement.

                                       19
<PAGE>
 
          In the case of a Shelf Registration Statement, the Company and the
Guarantors may (as a condition to such Holder's participation in the Shelf
Registration) require each Holder of Registrable Securities to furnish to the
Company such information regarding the Holder and the proposed distribution by
such Holder of such Registrable Securities as the Company and the Guarantors may
from time to time reasonably request in writing.  The Company may exclude from
such registration the Registrable Securities of any Holder who unreasonably
fails to furnish such information within a reasonable time after receiving such
request.  Each Holder as to which any Shelf Registration Statement is being
effected agrees to furnish promptly to the Company all information required to
be disclosed in order to make the information previously furnished to the
Company by such Holder not materially misleading.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company and the Guarantors of the
happening of any event or the discovery of any facts, each of the kind described
in Section 3(e)(ii)-(vii), such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(k), and, if so directed by the Company and the Guarantors, such Holder
will deliver to the Company and the Guarantors (at their expense) all copies in
such Holder's possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities current at
the time of receipt of such notice.  If the Company and the Guarantors shall
give any such notice to suspend the disposition of Registrable Securities
pursuant to a Shelf Registration Statement as a result of the happening of any
event or the discovery of any facts, each of the kind described in Section
3(e)(ii)-(vii), the Company and the Guarantors shall use their best efforts to
file and have declared effective (if an amendment) as soon as practicable an
amendment or supplement to the Shelf Registration Statement and shall extend the
period during which the Shelf Registration Statement shall be maintained
effective pursuant to this Agreement by the number of days during the period
from and including the date of the giving of such notice to and including the
date when the Holders shall have received copies of the supplemented or amended
Prospectus necessary to resume such dispositions.

          In the event that the Company and the Guarantors fail to effect the
Exchange Offer or file any Shelf Registration Statement and maintain the
effectiveness of any Shelf Registration Statement as provided herein, the
Company and the Guarantors shall not file any Registration Statement with
respect to any securities (within the meaning of Section 2(1) of the 1933 Act)
of the Company and the Guarantors other than Registrable Securities.

          If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage such offering will be
selected by the Majority Holders of such Registrable Securities included in such
offering and shall be acceptable to the Company and the Guarantors.  No Holder
of Registrable Securities

                                       20
<PAGE>
 
may participate in any underwritten registration hereunder unless such Holder
(a) agrees to sell such Holder's Registrable Securities on the basis provided in
any underwriting arrangements approved by the persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements.

          4.   Indemnification; Contribution.

          (a)  The Company and the Guarantors, jointly and severally, agree to
indemnify and hold harmless the Initial Purchasers, each Holder, each
Participating Broker-Dealer, each Person who participates as an underwriter (any
such Person being an "Underwriter") and each Person, if any, who controls any
Holder or Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

               (i)   against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any Registration
     Statement (or any amendment or supplement thereto) pursuant to which
     Exchange Securities or Registrable Securities were registered under the
     1933 Act, including all documents incorporated therein by reference, or the
     omission or alleged omission therefrom of a material fact required to be
     stated therein or necessary to make the statements therein not misleading,
     or arising out of any untrue statement or alleged untrue statement of a
     material fact contained in any Prospectus (or any amendment or supplement
     thereto) or the omission or alleged omission therefrom of a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

               (ii)  against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, to the extent of the aggregate amount paid
     in settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     4(d)) any such settlement is effected with the written consent of the
     Company and the Guarantors; and

               (iii) against any and all expense whatsoever, as incurred
     (including the fees and disbursements of counsel chosen by any indemnified
     party), reasonably incurred in investigating, preparing or defending
     against any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under subparagraph (i) or (ii) above; provided, however, that
     this indemnity agreement shall not apply to any

                                       21
<PAGE>
 
     loss, liability, claim, damage or expense to the extent arising out of any
     untrue statement or omission or alleged untrue statement or omission made
     in reliance upon and in conformity with written information furnished to
     the Company and the Guarantors by the Initial Purchasers, such Holder, such
     Participating Broker-Dealer or Underwriter expressly for use in any
     Registration Statement (or any amendment thereto) or any Prospectus (or any
     amendment or supplement thereto); provided, further, that the Company will
     not be liable to any Initial Purchaser, Holder (in its capacity as Holder),
     Participating Broker-Dealer or Underwriter (or any person who controls such
     party within the meaning of Section 15 of the 1933 Act or Section 20 of the
     1934 Act) with respect to any such untrue statement or alleged untrue
     statement or omission or alleged omission made in any preliminary
     Prospectus to the extent that the Company shall sustain the burden of
     proving that any such loss, liability, claim, damage or expense resulted
     from the fact that such Initial Purchaser, Holder (in its capacity as
     Holder), Participating Broker-Dealer or Underwriter, as the case may be,
     sold Securities to a Person to whom such Initial Purchaser, Holder (in its
     capacity as Holder), Participating Broker-Dealer or Underwriter, as the
     case may be, failed to send or give, at or prior to the written
     confirmation of the sale of such Securities a copy of the final Prospectus
     (as amended or supplemented) if the Company has previously furnished copies
     thereof (sufficiently in advance of the closing of such sale to allow for
     distribution of the final Prospectus in a timely manner) to such Initial
     Purchaser, Holder (in its capacity as Holder), Participating Broker-Dealer
     or Underwriter, as the case may be, and the loss, liability, claim, damage
     or expense of such Initial Purchaser Holder (in its capacity as a Holder),
     Participating Broker-Dealer or Underwriter, as the case may be, resulted
     solely from an untrue statement or omission or alleged untrue statement or
     omission of a material fact contained in or omitted from such preliminary
     Prospectus which was corrected in the final Prospectus (as amended or
     supplemented).

          (b) Each Holder severally, but not jointly, agrees to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers, each
Underwriter and the other selling Holders, and each of their respective
directors and officers, and each Person, if any, who controls the Company, the
Guarantors, the Initial Purchasers, any Underwriter or any other selling Holder
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act,
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in Section 4(a), as incurred, but only with respect to
untrue statements or omissions, or alleged untrue statements or omissions, made
in any Registration Statement (or any amendment thereto) or any Prospectus
included therein (or any amendment or supplement thereto) in reliance upon and
in conformity with written information with respect to such Holder furnished to
the Company and the Guarantors by such Holder expressly for use in any
Registration Statement (or any amendment thereto) or such Prospectus (or any
amendment or supplement thereto); provided, however, that no such Holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Shelf Registration Statement.

                                       22
<PAGE>
 
          (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action or proceeding commenced
against it in respect of which indemnity may be sought hereunder, but failure so
to notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement.  In case any
such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party; provided, however,
that if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 4 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that in
connection with such action the indemnifying party shall not be liable for the
expenses of more than one separate counsel (in addition to local counsel) in any
one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances
representing the indemnified parties under subsection (a) of this Section 4 who
are parties to such action or actions) or (ii) the indemnifying party does not
promptly retain counsel satisfactory to the indemnified party or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party.  After such notice from the
indemnifying party to such indemnified party, the indemnified party will not be
liable for the costs and expenses of any settlement of such action effected by
such indemnified party without the consent of the indemnifying party.  No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 4 (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to

                                       23
<PAGE>
 
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

          (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

          (e) If the indemnification provided for in this Section 4 is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the Company and the Guarantors on the one hand and the
Holders and the Initial Purchasers each on the other hand in connection with the
statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations.

     The relative fault of the Company and the Guarantors on the one hand and
the Holders and the Initial Purchasers each on the other hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company and the
Guarantors, the Holders or the Initial Purchasers and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

     The Company, the Guarantors, the Holders and the Initial Purchasers agree
that it would not be just and equitable if contribution pursuant to this Section
4 were determined by pro rata allocation (even if the Initial Purchasers were
treated as one entity and the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 4.  The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 4 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

                                       24
<PAGE>
 
     Notwithstanding the provisions of this Section 4, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.

     No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 4, each Person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Company, and each Person,
if any, who controls the Company and each Guarantor, as the case may be, within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company and such Guarantor, as the
case may be.  The Initial Purchasers' respective obligations to contribute
pursuant to this Section 4 are several in proportion to the principal amount of
Securities set forth opposite their respective names in Schedule A to the
Purchase Agreement and not joint.

          5.   Miscellaneous.

          5.1  Rule 144 and Rule 144A.  For so long as the Company is subject to
the reporting requirements of Section 13 or 15 of the 1934 Act, the Company and
the Guarantors covenant that they will file the reports required to be filed by
them under the 1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules
and regulations adopted by the SEC thereunder.  If the Company ceases to be so
required to file such reports, the Company and the Guarantors covenant that they
will upon the request of any Holder of Registrable Securities (a) make publicly
available such information as is necessary to permit sales pursuant to Rule 144
promulgated under the 1933 Act, (b) deliver such information to a prospective
purchaser as is necessary to permit sales pursuant to Rule 144A promulgated
under the 1933 Act and take such further action as any Holder of Registrable
Securities may reasonably request and (c) take such further action that is
reasonable in the circumstances, in each case, to the extent required from time
to time to enable such Holder to sell its Registrable Securities without
registration under the 1933 Act within the limitation of the exemptions provided
by (i) Rule 144 promulgated under the 1933 Act, as such Rule may be amended from
time to time, (ii) Rule 144A promulgated under the 1933 Act, as such Rule may be
amended from time to time or (iii) any similar rules or regulations hereafter
adopted by the SEC.  Upon the request of any Holder of Registrable Securities,
the Company and the Guarantors will deliver to such Holder a written statement
as to whether they have complied with such requirements.

          5.2  No Inconsistent Agreements.  The Company and the Guarantors have
not entered into, and the Company and the Guarantors will not after the date of

                                       25
<PAGE>
 
this Agreement enter into, any agreement which is inconsistent with the rights
granted to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof.  The rights granted to the Holders
hereunder do not and will not in any way for the term of this Agreement conflict
with the rights granted to the holders of the Company's and the Guarantors'
other issued and outstanding securities under any such agreements.

          5.3  Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Guarantors have obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure.

          5.4  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered first-
class mail, telex, facsimile, or any courier guaranteeing overnight delivery (a)
if to a Holder, at the most current address given by such Holder to the Company
and the Guarantors by means of a notice given in accordance with the provisions
of this Section 5.4, which address initially is the address set forth in the
Purchase Agreement with respect to the Initial Purchasers and (b) if to an
Initial Purchaser, at the most current address given by such Initial Purchaser
to the Company and the Guarantors by means of a notice given in accordance with
the provisions of this Section 5.4, which address initially is the address set
forth in the Purchase Agreement with respect to such Initial Purchaser and (c)
if to the Company and the Guarantors, initially at the Company's address set
forth in the Purchase Agreement, and thereafter at such other address of which
notice is given in accordance with the provisions of this Section 5.4.

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two business days
after being deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt is acknowledged, if sent by facsimile; and on the
next business day if timely delivered to an air courier guaranteeing overnight
delivery.

          Copies of all such notices, demands or other communications shall be
concurrently delivered by the person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.

          5.5  Successor and Assigns.  This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture.  If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or

                                       26
<PAGE>
 
otherwise, such Registrable Securities shall be held subject to all of the terms
of this Agreement, and by taking and holding such Registrable Securities such
person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and provisions of this Agreement, including the restrictions on
resale set forth in this Agreement and, if applicable, the Purchase Agreement,
and such person shall be entitled to receive the benefits hereof.

          5.6  Third Party Beneficiaries.  The Initial Purchasers (even if the
Initial Purchasers are not Holders of Registrable Securities) shall be third
party beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Holders, on the other hand, and shall have
the right to enforce such agreements directly to the extent they deem such
enforcement necessary or advisable to protect their rights or the rights of
Holders hereunder.  Each Holder of Registrable Securities shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights hereunder.

          5.7. Specific Enforcement.  Without limiting the remedies available to
the Initial Purchasers and the Holders, the Company and the Guarantors
acknowledge that any failure by the Company and the Guarantors to comply with
their obligations under Sections 2.1 through 2.4 may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it would not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Guarantors' obligations under
Sections 2.1 through 2.4; provided, however, with respect to any failures by the
Company and the Guarantors to comply with Section 2.1 or Section 2.2, such
relief shall not be available to any Holder who fails to make the required
representations in Section 2.1 or 3(f), as applicable.

          5.8. Restriction on Resales.  Until the expiration of two years after
the original issuance of the Securities and the Guarantees, the Company and the
Guarantors will not, and will cause their "affiliates" (as such term is defined
in Rule 144(a)(l) promulgated under the 1933 Act) not to, resell any Securities
which are "restricted securities" (as such term is defined under Rule 144(a)(3)
promulgated under the 1933 Act) that have been reacquired by any of them and
shall immediately upon any purchase of any such Securities submit such
Securities to the Trustee for cancellation.

          5.9  Counterparts.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                                       27
<PAGE>
 
          5.10  Headings.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          5.11 GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICT OF LAWS THEREOF.

          5.12 Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of the

Ladies and Gentlemen:

     We have acted as counsel for Newpark Resources, Inc., a Delaware
corporation (the "Company"), and its subsidiaries (as "Guarantors" as defined in
the Registration Rights Agreement, dated December 10, 1997 (the "Registration
Rights Agreement"), among the Company, the Guarantors and the Initial Purchasers
(as defined below)), in connection with the sale by the Company to the Initial
Purchasers of $125,000,000 aggregate principal amount of 8-5/8% Senior
Subordinated Notes due 2007 (the "Notes") of the Company pursuant to the
Purchase Agreement dated December 10, 1997 (the "Purchase Agreement") among the
Company, the Guarantors and Merrill Lynch, Pierce, Fenner & Smith Incorporated,
Deutsche Morgan Grenfell Inc. and Salomon Brothers Inc (collectively, the
"Initial Purchasers") and the filing by the Company of an Exchange Offer
Registration Statement (the "Registration Statement") in connection with an
Exchange Offer to be effected pursuant to the Registration Rights Agreement.
This opinion is furnished to you pursuant to Section 3(f)(B) of the Registration
Rights Agreement.  Unless otherwise defined herein, capitalized terms used in
this opinion that are defined in the Registration Rights Agreement are used
herein as so defined.

     We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion.  In rendering this opinion, as to
all matters of fact relevant to this opinion, we have assumed the completeness
and accuracy of, and are relying solely upon, the representations and warranties
of the Company and the Guarantors set forth in the Purchase Agreement and the
statements set forth in certificates of public officials and officers of the
Company and the Guarantors, without making any independent investigation or
inquiry with respect to the completeness or accuracy of such representations,
warranties or statements, other than a review of the certificate of
incorporation, by-laws, charter documents and relevant minute books of the
Company and the Guarantors.


                                      A-1
<PAGE>
 
     Based on and subject to the foregoing, we are of the opinion that:

          1.   The Exchange Offer Registration Statement and the Prospectus
(other than the financial statements, notes or schedules thereto and other
financial data and supplemental schedules included or incorporated by reference
therein or omitted therefrom and the Form T-1, as to which we need express no
opinion), comply as to form in all material respects with the requirements of
the 1933 Act and the applicable rules and regulations promulgated under the 1933
Act.

          2.   We have participated in the preparation of the Registration
Statement and the Prospectus and in the course thereof have had discussions with
representatives of the Underwriters, officers and other representatives of the
Company, and Deloitte & Touche LLP, the Company's independent public
accountants, during which the contents of the Registration Statement and the
Prospectus were discussed.  We have not, however, independently verified and are
not passing upon, and do not assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Registration
Statement and the Prospectus.  Based on our participation as described above,
nothing has come to our attention that would lead us to believe that the
Registration Statement (except for financial statements and schedules and other
financial data included therein as to which we make no statement) contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or that the Prospectus or any amendment or supplement thereto (except for
financial statements and schedules and other financial data included therein, as
to which we need make no statement), at the time the Prospectus was issued, at
the time any such amended or supplemented Prospectus was issued or at the
Closing Time, included or includes an untrue statement of a material fact or
omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     This opinion is being furnished to you solely for your benefit in
connection with the transactions contemplated by the Registration Rights
Agreement, and may not be used for any other purpose or relied upon by any
person other than you.  Except with our prior written consent, the opinions
herein expressed are not to be used, circulated, quoted or otherwise referred to
in connection with any transactions other than those contemplated by the
Registration Rights Agreement by or to any other person.

                         Very truly yours,

     RE:  REGISTRATION STATEMENT ON FORM S-4

Gentlemen:

     We have acted as counsel to Newpark Resources, Inc., a Delaware corporation
(the "Company"), and certain of its subsidiaries in connection with the 
Registration Statement on Form S-4 (the "Registration Statement") filed by the 
Company and such subsidiaries under the Securities Act of 1933, as amended (the 
"Securities Act"), with respect to $125,000,000 aggregate principal amount of 
the Company's 8 5/8% Senior Subordinated Notes Due 2007, Series B (the "Exchange
Notes") and the related guarantees (the "Guarantees") of the Company's 
subsidiaries named as additional registrants in the Registration Statement (the 
"Guarantors").  The Exchange Notes and the Guarantees will be offered in 
exchange for the Company's issued and outstanding 8 5/8% Senior Subordinated 
Notes Due 2007, Series A (the "Existing Notes") and related guarantees, all as 
described in the Registration Statement.  The Exchange Notes are proposed to be 
issued in accordance with the provisions of the Indenture, dated as of December 
17, 1997 (the "Indenture"), between the Company, the Guarantors and State Street
Bank and Trust Company, as Trustee.

     In arriving at the opinions expressed below, we have examined the
Registration Statement, the Prospectus contained therein, the Indenture, which
is filed as an exhibit to the Registration Statement, and the originals or
copies certified or otherwise identified to our satisfaction of such corporate
records and such other documents and certificates of public officials and
officers and representatives of the Company and the Guarantors as we have deemed
necessary or advisable for the purposes of this opinion. In such examination, we
have assumed and have not verified (i) that the signatures on all documents that
we have examined are genuine, (ii) the authenticity of all documents submitted
to us as originals, (iii) the conformity with the authentic originals of all
documents submitted to us as certified, photostatic or faxed copies, and (iv)
that all documents in respect of which forms were filed with the Securities and

     Based upon the foregoing, and subject to the qualifications and limitations
stated herein, we are of the opinion that:

     1.   When (a) the Exchange Notes have been exchanged for Existing Notes in 
the manner described in the Registration Statement, (b) the Exchange Notes have 
been duly executed, authenticated, issued and delivered in accordance with the 
terms of the Indenture and (c) the Indenture has been duly qualified under the 
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), the 
Exchange Notes will be legally issued and constitute valid and legally binding 
obligations of the Company, enforceable against the Company in accordance with 
the terms of the Indenture and the Exchange Notes.

     2.   When (a) the Exchange Notes have been exchanged for Existing Notes in 
the manner described in the Registration Statement, (b) the Exchange Notes and 
the Guarantees have been duly executed, authenticated, issued and delivered in 
accordance with the terms of the Indenture and (c) the Indenture has been duly 
qualified under the Trust Indenture Act, the Guarantees will constitute valid 
and legally binding obligations of the Guarantors, enforceable against each such
Guarantor in accordance with the terms of such Guarantor's respective Guarantee.

     The opinions expressed above with respect to the enforceability of the 
Exchange Notes and the Guarantees may be limited by applicable bankruptcy, 
insolvency, fraudulent conveyance, fraudulent transfer, reorganization, 
moratorium and other similar laws relating to or affecting creditors' rights 
generally and general principles of equity (including, without limitation, 
concepts of materiality, reasonableness, good faith and fair dealing and the 
possible unavailability of specific performance, injunctive relief or other 
equitable remedies), regardless of whether considered in a proceeding at law or 
in equity.

     We are members of the Bar of the State of California and the foregoing 
opinions are limited to the laws of the State of California, the federal laws of
the United States of America and the General Corporation Law of the State of 
Delaware.  Although we are not admitted to practice law in the State of

Ladies and Gentlemen:

     Newpark Resources, Inc., a Delaware corporation (the "Company"), and each
of the Guarantors listed on Schedule B hereto (the "Guarantors") confirm their
agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and each of the other Initial Purchasers named in
Schedule A hereto (collectively, the "Initial Purchasers", which term shall also
include any initial purchaser substituted as hereinafter provided in Section 11
hereof), for whom Merrill Lynch is acting as representative (in such capacity,
the "Representative"), with respect to (i) the issue and sale by the Company and
the purchase by the Initial Purchasers, acting severally and not jointly, of the
respective principal amounts set forth in said Schedule A of $125,000,000
aggregate principal amount of the Company's Senior Subordinated Notes due 2007
(the "Securities") and (ii) the issue and sale by the Guarantors and the
purchase by the Initial Purchasers, acting severally and not jointly, of the
senior subordinated guarantees (the "Guarantees") of the Company's obligations
under the Securities.  The Securities and the Guarantees are to be issued
pursuant to an indenture dated as of December 17, 1997 (the "Indenture"), among
the Company, the Guarantors and State Street Bank and Trust Company, as trustee
(the "Trustee").  Securities issued in book-entry form will be issued to Cede &
Co. as nominee of The Depository Trust Company ("DTC") pursuant to a letter
agreement, to be dated as of the Closing Time (as defined in Section 2(b)) (the
"DTC Agreement"), among the Company, the Guarantors, the Trustee and DTC.

     The Company and the Guarantors understand that the Initial Purchasers
propose to make an offering of the Securities and the Guarantees on the terms
and in the manner set forth herein and agree that the Initial Purchasers may
resell, subject to the conditions set forth herein, all or a portion of the
Securities and the Guarantees to purchasers ("Subsequent Purchasers") at any
time after the date of this Agreement.  The Securities and the Guarantees are to
be offered and sold through the Initial Purchasers without being registered
under the Securities Act of 1933, as amended (the

                                       2
<PAGE>
 
"1933 Act"), in reliance upon exemptions therefrom.  Pursuant to the terms of
the Securities, the Guarantees and the Indenture, investors that acquire
Securities and Guarantees may resell or otherwise transfer such Securities and
Guarantees only if such Securities and Guarantees are hereafter registered under
the 1933 Act or if an exemption from the registration requirements of the 1933
Act is available (including the exemption afforded by Rule 144A ("Rule 144A") or
Regulation S ("Regulation S") of the rules and regulations promulgated under the
1933 Act by the Securities and Exchange Commission (the "Commission")).

     The Company and the Guarantors have prepared and delivered to each Initial
Purchaser copies of a preliminary offering memorandum dated November 21, 1997
(the "Preliminary Offering Memorandum") and have prepared and will deliver to
each Initial Purchaser, on the date hereof or the next succeeding day, copies of
a final offering memorandum dated December 17, 1997 (the "Final Offering
Memorandum"), each for use by such Initial Purchaser in connection with its
solicitation of purchases of, or offering of, the Securities and the Guarantees.
"Offering Memorandum" means, with respect to any date or time referred to in
this Agreement, the most recent offering memorandum (whether the Preliminary
Offering Memorandum or the Final Offering Memorandum, or any amendment or
supplement to either such document), including exhibits thereto and any
documents incorporated therein by reference, which has been prepared and
delivered by the Company and the Guarantors to the Initial Purchasers in
connection with their solicitation of purchases of, or offering of, the
Securities and the Guarantees.

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the Offering
Memorandum (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
are incorporated by reference in the Offering Memorandum; and all references in
this Agreement to amendments or supplements to the Offering Memorandum shall be
deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934, as amended (the "1934 Act"), which is incorporated by
reference in the Offering Memorandum.

     The holders of the Securities and the Guarantees will be entitled to the
benefits of the registration rights agreement to be dated as of the Closing Time
referred to in Section 2(b) hereof (the "Registration Rights Agreement"), among
the Company, the Guarantors and the Initial Purchasers, pursuant to which the
Company will agree to file, as soon as practicable after the Closing Time but in
any event within 45 days of the Closing Time, a registration statement with the
Commission registering the Exchange Securities (as defined in the Registration
Rights Agreement), consisting of the 8-5/8% Senior Subordinated Notes due 2007,
Series B, to be issued by the Company (the "Exchange Notes") and the related
guarantees to be issued by the Guarantors (the "Exchange Guarantees"), under the
1933 Act.

     SECTION 1.  Representations and Warranties.

     (a) Representations and Warranties by the Company and the Guarantors.  The
Company and each of the Guarantors, jointly and severally, represent and warrant
to each Initial Purchaser as of the date hereof and as of the Closing Time and
agree with each Initial Purchaser as follows:

          (i) Similar Offerings.  The Company and the Guarantors have not,
     directly or indirectly, solicited any offer to buy or offered to sell, and
     will not, directly or indirectly, solicit any offer to buy or offer to
     sell, in the United States or to any United States citizen or resident, any
     security which is or would be integrated with the sale of the Securities
     and the Guarantees in a manner that would require the Securities and the
     Guarantees to be registered under the 1933 Act.

          (ii) Offering Memorandum.  The Offering Memorandum does not, and at
     the Closing Time will not, include an untrue statement of a material fact
     or omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; provided, that this representation, warranty and agreement
     shall not apply to statements in or omissions from the Offering Memorandum
     made in reliance upon and in conformity with information furnished to the
     Company in writing by any Initial Purchaser through Merrill Lynch expressly
     for use in the Offering Memorandum.  The documents incorporated by
     reference or deemed to be incorporated by reference in the Offering
     Memorandum at the time they were or hereafter are filed with the Commission
     (or as subsequently amended) complied and will comply in all material
     respects with the applicable requirements of the 1934 Act and the
     applicable rules and regulations of the Commission thereunder and, when
     read together with the other information in the Offering Memorandum, at the
     date of the Offering Memorandum and at the Closing Time, did not and will
     not include an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

          (iii)  Independent Accountants.  The accountants who certified the
     financial statements and supporting schedules included or incorporated by
     reference in the Offering Memorandum are independent certified public
     accountants with respect to the Company, the Guarantors and their
     respective subsidiaries within the meaning of Regulation S-X promulgated
     under the 1933 Act.

          (iv) Financial Statements.  The financial statements, together with

     its consolidated subsidiaries for the periods specified; said financial
     statements have been prepared in conformity with generally accepted
     accounting principles ("GAAP") applied on a consistent basis throughout the
     periods involved, except as otherwise indicated therein.  The selected
     financial data and the summary financial information included in the
     Offering Memorandum present fairly the information shown therein and,

     consistent with that of the audited financial statements included in the

     in the condition, financial or otherwise, or in the earnings, business
     affairs or business prospects of the Company and its subsidiaries
     considered as one enterprise (a "Material Adverse Effect"), whether or not
     arising in the ordinary course of business, (B) there have been no
     transactions entered into by the Company or any of its subsidiaries, other
     than those in the ordinary course of business, which are material with

     duly qualified as a foreign corporation to transact business and is in good
     standing in each other jurisdiction in which such qualification is
     required, whether by reason of the ownership or leasing of property or the
     conduct of business, except where the failure so to qualify or to be in
     good standing would not result in a Material Adverse Effect.

          (vii)  Good Standing of Subsidiaries.  Each subsidiary of the Company,
     (each a "Subsidiary" and, collectively, the "Subsidiaries") has been duly
     organized or formed and is validly existing as a corporation, partnership
     or limited liability company under the laws of the jurisdiction of its
     formation.  Each Subsidiary

<PAGE>
 
     that is a corporation or limited liability company is in good standing
     under the laws of the jurisdiction of its formation.  Each Subsidiary has
     the power and authority to own, lease and operate its properties and to
     conduct its business as described in the Offering Memorandum and is duly
     qualified or registered as a foreign entity to transact business in each
     jurisdiction in which such qualification is required, whether by reason of
     the ownership or leasing of property or the conduct of business, and, with
     respect to each Subsidiary that is a corporation or limited liability
     company, is in good standing in each such jurisdiction, except where the
     failure so to qualify or to be in good standing would not result in a
     Material Adverse Effect; except as otherwise disclosed in the Offering
     Memorandum, all of the issued and outstanding capital stock of each
     Subsidiary that is a corporation has been duly authorized and validly
     issued, is fully paid and non-assessable and is owned by the Company,
     directly or through the Subsidiaries, free and clear of any security
     interest, mortgage, pledge, lien, encumbrance, claim or equity; none of the
     outstanding shares of capital stock of the Subsidiaries that are
     corporations was issued in violation of any preemptive or similar rights
     arising by operation of law, or under the charter or by-laws of any
     Subsidiary or under any agreement to which the Company or any Subsidiary is
     a party.  The partner interests in each Subsidiary that is a limited
     partnership and the membership interests in each Subsidiary that is a
     limited liability company have been validly issued and fully paid and are
     owned by the Company, directly or through the Subsidiaries, free and clear

     Schedule B attached hereto.

          (viii)  Capitalization.  The authorized, issued and outstanding
     capital stock of the Company was at the date indicated in the Offering
     Memorandum as set forth in the financial statements, including the
     schedules and notes, included in the Offering Memorandum (except for
     subsequent issuances, if any, pursuant to acquisition transactions or
     employee benefit plans referred to in the Offering Memorandum or pursuant
     to the exercise of convertible securities or options referred to in the
     Offering Memorandum).  The shares of issued and outstanding capital stock
     of the Company have been duly authorized and validly issued and are fully
     paid and non-assessable; and none of the outstanding shares of capital
     stock of the Company was issued in violation of the preemptive or other
     similar rights of any securityholder of the Company arising by operation of
     law, under the charter of by-laws of the Company, under any agreement to
     which the Company or any of the Subsidiaries is a party or otherwise.

          (ix) Authorization of Agreements.  This Agreement, the Registration
     Rights Agreement and the DTC Agreement have been duly authorized by the
     Company, and this Agreement and the Registration Rights Agreement have each
     been duly authorized by each of the Guarantors.  This Agreement has been
     duly executed and delivered by the Company and each of the Guarantors.  As
     of the Closing Time (A) the Registration Rights Agreement will have been
     duly executed and delivered by the Company and each of the Guarantors and
     (B) the

                                       6
<PAGE>
 
     DTC Agreement will have been duly executed and delivered by the Company.
     Upon the execution and delivery thereof by the Company and each of the
     Guarantors, the Registration Rights Agreement will constitute a valid and
     binding obligation of the Company and each of the Guarantors, enforceable
     against the Company and each of the Guarantors in accordance with its
     terms, except as the enforcement thereof may be limited by bankruptcy,
     insolvency (including, without limitation, all laws relating to fraudulent
     transfers), reorganization, moratorium or other similar laws relating to or
     affecting enforcement of creditors' rights generally, or by general
     principles of equity (regardless of whether enforcement is considered in a
     proceeding in equity or at law) (the "Enforcement Exception").  Upon the
     execution and delivery thereof by the Company, the DTC Agreement will
     constitute a valid and binding obligation of the Company, enforceable
     against the Company in accordance with its terms, except as the enforcement
     thereof may be limited by the Enforcement Exception.

          (x) Authorization of the Indenture.  The Indenture has been duly
     authorized by the Company and each of the Guarantors and, at the Closing
     Time, will have been duly executed and delivered by the Company and each of

     each of the Guarantors in accordance with its terms, except as the
     enforcement thereof may be limited by the Enforcement Exception.

          (xi) Authorization of the Securities and the Guarantees.  The
     Securities and the Guarantees have been duly authorized by the Company and,
     at the Closing Time, will have been duly executed by the Company and, when
     authenticated in the manner provided for in the Indenture and delivered
     against payment of the purchase price therefor, will constitute valid and
     binding obligations of the Company, enforceable against the Company in
     accordance with their terms, except as the enforcement thereof may be
     limited by the Enforcement Exception, and will be in the form contemplated
     by, and entitled to the benefits of, the Indenture.  The Guarantees have
     been duly authorized by the Guarantors and, at the Closing time, will have
     been duly executed by the Guarantors and, when authenticated in the manner
     provided for in the Indenture and delivered against payment of the purchase
     price therefor, will constitute valid and binding obligations of the
     Guarantors, enforceable against the Guarantors in accordance with their
     terms, except as the enforcement thereof may be limited by the Enforcement
     Exception, and will be in the form contemplated by, and entitled to the
     benefits of, the Indenture.  The Exchange Notes have been duly authorized
     by the Company and the Exchange Guarantees have been duly authorized by
     each of the Guarantors and, when executed and authenticated and issued and
     delivered by the Company and each of the Guarantors in exchange for the
     Securities and the Guarantees, respectively, pursuant to the Exchange Offer
     (as defined in the Registration Rights Agreement), will constitute valid
     and binding obligations of the Company and each of the Guarantors, as the
     case may be, enforceable against the Company

                                       7
<PAGE>
 
     and each of the Guarantors, as the case may be, in accordance with their
     respective terms, except as the enforcement thereof may be limited by the
     Enforcement Exception.

          (xii)  Description of the Securities, the Guarantees and the
     Indenture. The Securities, the Guarantees and the Registration Rights
     Agreement will conform in all material respects to the respective
     statements relating thereto contained in the Offering Memorandum and will
     be in substantially the respective forms previously delivered to the
     Initial Purchasers.  The Exchange Securities will conform in all material
     respects to the statements relating thereto contained in the Offering
     Memorandum and the Registration Statement at the time it becomes effective.
     There are no contracts or documents which are required to be described in a
     registration statement on Form S-1 under the 1933 Act which have not been
     described in the Offering Memorandum.

          (xiii)  Absence of Defaults and Conflicts.  Neither the Company nor
     any of the Subsidiaries is in violation of its charter or by-laws or in
     default in the performance or observance of any obligation, agreement,
     covenant or condition contained in any contract, indenture, mortgage, deed
     of trust, loan or credit agreement, note, lease or other agreement or
     instrument to which the Company or any of the Subsidiaries is a party or by
     which it or any of them may be bound, or to which any of the property or
     assets of the Company or any of the Subsidiaries is subject (collectively,
     "Agreements and Instruments") or has violated or is in violation of any
     applicable law, statute, rule, regulation, judgment, order, writ or decree
     of any government, government instrumentality or court, domestic or
     foreign, having jurisdiction over the Company or any of the Subsidiaries or
     any of their assets or properties, except in each case for such defaults or
     violations that have been waived or would not result in a Material Adverse
     Effect; and the execution, delivery and performance of this Agreement, the
     Registration Rights Agreement, the Indenture, the DTC Agreement, the
     Securities, the Guarantees, the Exchange Securities and any other agreement
     or instrument entered into or issued or to be entered into or issued by the
     Company or any of the Guarantors in connection with the transactions
     contemplated hereby or thereby or in the Offering Memorandum and the
     consummation of the transactions contemplated herein and in the Offering
     Memorandum (including the issuance and sale of the Securities and the
     Guarantees and the use of the proceeds from the sale of the Securities and
     the Guarantees as described in the Offering Memorandum under the caption
     "Use of Proceeds") and compliance by the Company and the Guarantors with
     their respective obligations hereunder have been duly authorized by all
     necessary corporate action and do not and will not, whether with or without
     the giving of notice or passage of time or both, conflict with or
     constitute a breach of, or default or a Repayment Event (as defined below)
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of the Company or any of the
     Subsidiaries pursuant to, the Agreements and Instruments, nor will such
     action result in any violation of the provisions of the charter or by-laws
     of the Company

                                       8
<PAGE>
 
     or any of the Subsidiaries or any applicable law, statute, rule,
     regulation, judgment, order, writ or decree of any government, government
     instrumentality or court, domestic or foreign, having jurisdiction over the
     Company or any of the Subsidiaries or any of their assets or properties, to
     the extent that such conflict, breach or violation would result in a
     Material Adverse Effect; provided, however, that, for purposes of this
     representation and warranty only, the amendment to the Credit Facility (as
     defined below) as described in the Offering Memorandum shall be deemed to
     have been effective as of the date hereof.  As used herein, a "Repayment
     Event" means any event or condition which gives the holder of any note,
     debenture or other evidence of indebtedness (or any person acting on such
     holder's behalf) the right to require the repurchase, redemption or
     repayment of all or a portion of such indebtedness by the Company or any of
     the Subsidiaries which has not been repurchased, redeemed or repaid.

          (xiv)  Absence of Labor Dispute.  No labor dispute with the employees
     of the Company or any of the Subsidiaries exists or, to the knowledge of
     the Company and the Guarantors, is imminent, and the Company and the
     Guarantors are not aware of any existing or imminent labor disturbance by
     the employees of any of their or any of the Subsidiaries' principal
     suppliers, manufacturers, customers or contractors, which, in either case,
     may reasonably be expected to result in a Material Adverse Effect.

          (xv) Absence of Proceedings.  Except as disclosed in the Offering
     Memorandum, there is no action, suit, proceeding, inquiry or investigation
     before or by any court or governmental agency or body, domestic or foreign,
     now pending, or, to the knowledge of the Company or any Guarantor,
     threatened, against or affecting the Company or any Subsidiary thereof
     which might reasonably be expected to result in a Material Adverse Effect,
     or which might reasonably be expected to materially and adversely affect
     the properties or assets of the Company or any of the Subsidiaries or the
     consummation of this Agreement or the Registration Rights Agreement or the
     performance by the Company and the Guarantors of their respective
     obligations hereunder and thereunder or under the Indenture, the
     Registration Rights Agreement, the DTC Agreement, the Securities, the
     Guarantees or the Exchange Securities.  The aggregate of all pending legal
     or governmental proceedings to which the Company or any Subsidiary thereof
     is a party or of which any of their respective properties or assets is the
     subject which are not described in the Offering Memorandum, including
     ordinary routine litigation incidental to the business, could not
     reasonably be expected to result in a Material Adverse Effect.

          (xvi)  Possession of Intellectual Property.  The Company and the
     Subsidiaries own, possess or license, or, to the knowledge of the Company,
     can acquire on reasonable terms, adequate patents, patent rights, licenses,
     inventions, copyrights, know-how (including trade secrets and other
     unpatented and/or unpatentable proprietary or confidential information,
     systems or procedures), trademarks, service marks, trade names or other
     intellectual

                                       9
<PAGE>
 
     property (collectively, "Intellectual Property") necessary to carry on the
     business now operated by them, and neither the Company nor any of the
     Subsidiaries has received any notice or is otherwise aware of any
     infringement of or conflict with asserted rights of others with respect to
     any Intellectual Property (including Intellectual Property which is
     licensed) or of any facts or circumstances which would render any
     Intellectual Property invalid or inadequate to protect the interest of the
     Company or any of the Subsidiaries therein, and which infringement or
     conflict (if the subject of any unfavorable decision, ruling or finding) or
     invalidity or inadequacy, singly or in the aggregate, would reasonably be
     expected to result in a Material Adverse Effect.

          (xvii)  Absence of Further Requirements.  Except as disclosed in the
     Offering Memorandum, no filing with, or authorization, approval, consent,
     license, order, registration, qualification or decree of, any court or
     governmental authority or agency is necessary or required for the
     performance by the Company or any of the Guarantors of their respective
     obligations hereunder, in connection with the offering, issuance or sale of
     the Securities and the Guarantees hereunder or the consummation of the
     transactions contemplated by, or for the due execution, delivery or
     performance of, this Agreement, the Registration Rights Agreement, the
     Indenture, the DTC Agreement, the Securities, the Guarantees, the Exchange
     Securities or any other agreement or instrument entered into or issued or
     to be entered into or issued by the Company or any of the Subsidiaries in
     connection with the consummation of the transactions contemplated herein
     and in the Offering Memorandum (including the issuance and sale of the
     Securities and the Guarantees and the use of the proceeds from the sale of
     the Securities and the Guarantees as described in the Offering Memorandum
     under the caption "Use of Proceeds").

          (xviii)  Possession of Licenses and Permits.  The Company and the
     Subsidiaries possess such permits, licenses, approvals, consents and other
     authorizations (collectively, "Governmental Licenses") which are material
     to the Company and each of the Guarantors issued by the appropriate
     federal, state, local or foreign regulatory agencies or bodies necessary to
     conduct the business now operated by them respectively; the Company and the
     Subsidiaries are in compliance with the terms and conditions of all such
     Governmental Licenses and with the rules and regulations of the regulatory
     authorities having jurisdiction with respect thereto, except where the
     failure so to comply would not, singly or in the aggregate, have a Material
     Adverse Effect; all of the Governmental Licenses are valid and in full
     force and effect, except when the invalidity of such Governmental Licenses
     or the failure of such Governmental Licenses to be in full force and effect
     would not have a Material Adverse Effect; and neither the Company nor any
     of the Subsidiaries has received any notice of proceedings relating to the
     revocation or modification of any such Governmental Licenses, nor are
     there, to the knowledge of the Company or any Guarantor, pending or
     threatened actions, suits, claims or proceedings against the Company or any
     Subsidiary before any court, governmental agency or body or otherwise that,
     if

                                       10
<PAGE>
 
     successful, would limit, revoke, cancel, suspend or cause not to be renewed
     any Governmental License, in each case, which, singly or in the aggregate,
     if the subject of an unfavorable decision, ruling or finding, would result
     in a Material Adverse Effect.

          (xix)  Title to Property.  The Company and the Subsidiaries have good
     and marketable title to all real property owned by the Company and the
     Subsidiaries and good title to all other properties owned by them, in each
     case, free and clear of all mortgages, pledges, liens, security interests,
     claims, restrictions or encumbrances of any kind except such as (A) are
     described in the Offering Memorandum, including the financial statements
     and schedules and other information contained in the Offering Memorandum,
     or (B) do not, singly or in the aggregate, materially affect the value of
     such property and do not interfere with the use made and proposed to be
     made of such property by the Company or any of the Subsidiaries; and all of
     the leases and subleases material to the business of the Company and the
     Subsidiaries, considered as one enterprise, and under which the Company or
     any of the Subsidiaries holds properties described in the Offering
     Memorandum, are in full force and effect, and neither the Company nor any
     of the Subsidiaries has any notice of any material claim of any sort that
     has been asserted by anyone adverse to the rights of the Company or any of
     the Subsidiaries under any of the leases or subleases mentioned above, or
     affecting or questioning the rights of such the Company or any Subsidiary
     to the continued possession of the leased or subleased premises under any
     such lease or sublease.

          (xx) Tax Returns.  All United States federal income tax returns of the
     Company and the Subsidiaries required by law to be filed have been filed
     and all taxes shown by such returns or otherwise assessed, which are due
     and payable, have been paid, except assessments against which appeals have
     been or will be promptly taken and as to which adequate reserves have been
     provided.  The Company and the Subsidiaries have filed all other tax
     returns that are required to have been filed by them pursuant to applicable
     foreign, federal, state, local or other law except insofar as the failure
     to file such returns would not result in a Material Adverse Effect, and
     have paid all taxes due pursuant to such returns or pursuant to any
     assessment received by the Company and the Subsidiaries, except for such
     taxes, if any, as are being contested in good faith and by appropriate
     proceedings and as to which adequate reserves have been provided.  The
     charges, accruals and reserves on the books of the Company in respect of
     all federal, state, local and foreign tax liabilities of the Company and
     each Subsidiary for any years not finally determined are adequate to meet
     any assessments or reassessments for additional income tax that is
     reasonably expected to be payable for any years not finally determined,
     except to the extent of any inadequacy that would not result in a Material
     Adverse Effect.

          (xxi)  Insurance.  The Company and the Subsidiaries carry or are
     entitled to the benefits of insurance, with financially sound and reputable
     insurers, in

                                       11
<PAGE>
 
     such amounts and covering such risks as is generally maintained by
     companies of established repute engaged in the same or similar business,
     and all such insurance is in full force and effect.

          (xxii)  Solvency.  The Company and each of the Guarantors is, and
     immediately after the Closing will be, Solvent.  As used herein, the term
     "Solvent" means, with respect to the Company and each Guarantor, as the
     case may be, on a particular date, that on such date (A) the fair market
     value of the assets of the Company or such Guarantor is greater than the
     total amount of liabilities (including contingent liabilities) of the
     Company or such Guarantor, (B) the present fair salable value of the assets
     of the Company or such Guarantor is greater than the amount that will be
     required to pay the probable liabilities of the Company or such Guarantor
     on its debts as they become absolute and mature, (C) the Company or such
     Guarantor is able to realize upon its assets and pay its debts and other
     liabilities, including contingent obligations, as they mature and (D) the
     Company or such Guarantor does not have unreasonably small capital.

          (xxiii) Offering Material Distribution.  The Company and the
     Guarantors have not distributed and, prior to the later to occur of (i) the
     Closing Time and (ii) completion of the distribution of the Securities and
     the Guarantees, will not distribute any offering material in connection
     with the offering and sale of the Securities and the Guarantees other than
     the Offering Memorandum and other materials, if any, permitted by the 1933
     Act and approved by the Representative.

          (xxiv)  Related Party Transactions.  No relationship, direct or
     indirect, exists between or among any of the Company, the Guarantors or any
     affiliate of the Company or any Guarantor, on the one hand, and any
     director, officer, stockholder, customer or supplier of any of them, on the
     other hand, which is required by the 1933 Act or by the rules and
     regulations enacted thereunder to be described in a registration statement
     on Form S-1 which is not so described or is not described as required in
     the Offering Memorandum.

          (xxv)  Absence of Defaults on Senior Indebtedness.  No event of
     default exists under any contract, indenture, mortgage, loan agreement,
     note, lease or other agreement or instrument constituting Senior
     Indebtedness (as defined in the Indenture).

          (xxvi)  Environmental Laws.  Except as described in the Offering
     Memorandum and except such matters as would not, singly or in the
     aggregate, result in a Material Adverse Effect, (A) neither the Company nor
     any of the Subsidiaries is in violation of any federal, state, local or
     foreign statute, law, rule, regulation, ordinance, code, policy or rule of
     common law or any judicial or administrative interpretation thereof,
     including any judicial or administrative order, consent, decree or
     judgment, relating to pollution or protection of human health, the
     environment (including, without limitation, ambient air, surface

                                       12
<PAGE>
 
     water, groundwater, land surface or subsurface strata) or wildlife,
     including, without limitation, laws and regulations relating to the release
     or threatened release of chemicals, pollutants, contaminants, wastes, toxic
     substances, hazardous substances, petroleum or petroleum products
     (collectively, "Hazardous Materials") or to the manufacture, processing,
     distribution, use, treatment, storage, disposal, transport or handling of
     Hazardous Materials (collectively, "Environmental Laws"), (B) the Company
     and the Subsidiaries have all permits, authorizations and approvals
     required under any applicable Environmental Laws and are each in compliance
     with their requirements, (C) there are no pending or, to the knowledge of

severally and not jointly, and each Initial Purchaser, severally and not
jointly, agrees to purchase from the Company and the Guarantors, at the price
set forth in Schedule C, the aggregate principal amount of Securities set forth
in Schedule A opposite the name of such Initial Purchaser, plus any additional
principal amount of Securities which such

                                       14

Initial Purchaser may become obligated to purchase pursuant to the provisions of

Cede & Co. pursuant to the DTC Agreement, or physical certificates representing
the Securities and the Guarantees shall be registered in the names and
denominations requested by the Initial Purchasers, and in either case shall be

copies of the Preliminary Offering Memorandum, the Final Offering Memorandum and
any amendments and supplements thereto and documents incorporated by reference
therein as such Initial Purchaser may reasonably request.

     (b) Notice and Effect of Material Events.  The Company and the Guarantors

securities exchange or any other regulatory body in the United States or any
other jurisdiction, and (y) prior to the completion of the placement of the
Securities and the Guarantees by the Initial Purchasers as evidenced by a notice
in writing from the Initial Purchasers to the Company, any material changes in
or affecting the earnings, business affairs or business prospects of the Company
and the Subsidiaries which (i) make any statement in the Offering Memorandum
false or misleading or (ii) are not disclosed in the Offering Memorandum.  In
such event or if during such time any event shall occur as a result of which it
is necessary, in the reasonable opinion of the Company and the Guarantors, their
counsel, the Initial Purchasers or counsel for the Initial Purchasers, to amend
or supplement the Final Offering Memorandum in order that the Final Offering
Memorandum not include any untrue statement of a material fact or omit to state
a material fact necessary in order to make the statements therein not misleading
in the light of the circumstances then existing, the Company and the Guarantors
will forthwith amend or supplement the Final Offering Memorandum by preparing
and furnishing to each Initial Purchaser an amendment or amendments of, or a
supplement or supplements to, the Final Offering Memorandum (in form and
substance satisfactory in the reasonable opinion of counsel for the Initial
Purchasers) so that, as so amended or supplemented, the Final Offering
Memorandum will not include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances existing at the time it is delivered to a Subsequent
Purchaser, not misleading.

     (c) Amendment to Offering Memorandum And Supplements.  The Company and the
Guarantors will advise each Initial Purchaser promptly of any proposal to amend
or supplement the Offering Memorandum and will not effect such amendment or
supplement without the consent of the Initial Purchasers.  Neither the consent
of the Initial Purchasers to, nor the Initial Purchaser's delivery of, any such
amendment or supplement, shall constitute a waiver of any of the conditions set
forth in Section 5 hereof.

Company and the Guarantors will use their best efforts to qualify the Securities
and the Guarantees for offering and sale under the applicable securities laws of

qualifications in effect as long as reasonably required for the sale of the
Securities and the Guarantees to Subsequent Purchasers; provided, however, that
the Company and the Guarantors shall not be obligated to file any general
consent to service of process or to qualify as a foreign corporation or as a
dealer in securities in any jurisdiction in which it is not so qualified or to
subject itself to taxation in respect of doing business in any jurisdiction in
which it is not otherwise so subject.

     (e) Integration.  The Company and the Guarantors agree that they will not
and will cause their affiliates not to make any offer or sale of securities of
the Company or any Guarantor of any class if, as a result of the doctrine of
"integration" referred to in Rule 502 under the 1933 Act, such offer or sale
could be deemed to render invalid (for the purpose of (i) the sale of the
Securities and the Guarantees by the Company and the Guarantors to the Initial
Purchasers, (ii) the resale of the Securities and the Guarantees by the Initial
Purchasers to Subsequent Purchasers or (iii) the resale of the Securities and

purchase any option or contract to sell, grant any option, right or warrant for
the sale of, or otherwise dispose of or transfer, any debt securities or
guarantees of debt securities of the Company or file a registration statement
under the 1933 Act with respect to the foregoing (other than borrowings under
the Credit Facility, the Securities, the Guarantees and the Exchange
Securities).

     (i) DTC Clearance.  The Company and the Guarantors will use all reasonable
efforts in cooperation with the Initial Purchasers to permit the Securities and
the Guarantees to be eligible for clearance and settlement through DTC.

     Initial Purchasers or Affiliates thereof qualified to do so in the
     jurisdictions in which such offers or sales are made.  Each such offer or

     reasonably believes to be qualified institutional buyers (as defined in
     Rule 144A under the Securities Act) or (B) to non-U.S. persons outside the
     United States  whom the offeror or seller reasonably believes offers and
     sales of the Securities may be made in reliance upon Regulation S under the
     1933 Act.

          (ii) No General Solicitation.  The Securities and the Guarantees will
     be offered by approaching prospective Subsequent Purchasers on an

     States in connection with the offering of the Securities.

          (iii)  Purchases by Non-Bank Fiduciaries.  In the case of a non-bank
     Subsequent Purchaser of a Security or Guarantee acting as a fiduciary for
     one or more third parties, in connection with an offer and sale to such
     purchaser pursuant to clause (i) above, each third party shall, in the
     judgment of the applicable Initial Purchaser, be an institutional
     accredited investor as such term

                                       21
<PAGE>
 
     is defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D or a
     Qualified Institutional Buyer or a non-U.S. person outside the United
     States.

          (iv) Subsequent Purchaser Notification.  Each Initial Purchaser will
     take reasonable steps to inform, and cause each of its U.S. Affiliates to
     take reasonable steps to inform, persons acquiring Securities and
     Guarantees from such Initial Purchaser or affiliate, as the case may be, in
     the United States that the Securities and the Guarantees (A) have not been
     and will not be registered under the 1933 Act, (B) are being sold to them
     without registration under the 1933 Act in reliance on Rule 144A or in
     accordance with another exemption from registration under the 1933 Act, as
     the case may be, and (C) may not be offered, sold or otherwise transferred
     except (1) to the Company, (2) outside the United States in accordance with
     Rule 904 of Regulation S, or (3) inside the United States in accordance
     with (x) Rule 144A to a person whom the Seller reasonably believes is a
     Qualified Institutional Buyer that is purchasing such Securities and
     Guarantees for its own account or for the account of a Qualified
     Institutional Buyer to whom notice is given that the offer, sale or
     transfer is being made in reliance on Rule 144A or (y) the exemption from
     registration under the 1933 Act provided by Rule 144, if available.

          (v) Restrictions on Transfer.  The transfer restrictions set forth in
     Sections 202(a), 202(b), 305 and 307 of the Indenture, including the legend
     required thereby, shall apply to the Securities and the Guarantees except
     as otherwise agreed by the Company, the Guarantors and the Initial
     Purchasers. Following the sale of the Securities and the Guarantees by the
     Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof,
     the Initial Purchasers shall not be liable or responsible to the Company
     and the Guarantors for any losses, damages or liabilities suffered or
     incurred by the Company and the Guarantors, including any losses, damages
     or liabilities under the 1933 Act, arising from or relating to any resale
     or transfer of any Security, except for the indemnification obligations of
     the Initial Purchasers pursuant to Sections 7 and 8 hereof.

     (b) Covenants of the Company and the Guarantors.  The Company and the
Guarantors covenant with each Initial Purchaser as follows:

          (i) Due Diligence.  In connection with the original distribution of
     the Securities and the Guarantees, the Company and the Guarantors agree
     that, prior to any offer or resale of the Securities and the Guarantees by
     the Initial Purchasers, the Initial Purchasers and counsel for the Initial
     Purchasers shall have the right to make reasonable inquiries into the
     business of the Company and the Subsidiaries.  The Company and the
     Guarantors also agree to provide answers to each prospective Subsequent
     Purchaser of Securities and the Guarantees who so requests concerning the
     Company and the Subsidiaries (to the extent that such information is
     available or can be acquired and made available to prospective Subsequent
     Purchasers without unreasonable effort or

                                       22

     expense and to the extent the provision thereof is not prohibited by
     applicable law) and the terms and conditions of the offering of the
     Securities and the Guarantees, as provided in the Offering Memorandum.

          (ii) Integration.  The Company and the Guarantors agree that they will
     not and will cause their respective Affiliates not to make any offer or
     sale of securities of the Company or the Guarantors of any class if, as a
     result of the doctrine of "integration" referred to in Rule 502 promulgated
     under the 1933 Act, such offer or sale would render invalid (for the
     purpose of (i) the sale of the Securities and the Guarantees by the Company
     and the Guarantors to the Initial Purchasers, (ii) the resale of the
     Securities and the Guarantees by the Initial Purchasers to Subsequent
     Purchasers or (iii) the resale of the Securities and the Guarantees by such
     Subsequent Purchasers to others) the exemption from the registration
     requirements of the 1933 Act provided by Section 4(2) thereof or by Rule
     144A thereunder or otherwise.

          (iii)  Rule 144A Information.  The Company and the Guarantors agree
     that, in order to render the Securities and the Guarantees eligible for
     resale pursuant to Rule 144A under the 1933 Act, while any of the
     Securities and the Guarantees remain outstanding, they will make available,
     upon request, to any holder of Securities and the Guarantees or prospective
     purchasers of Securities and Guarantees the information specified in Rule
     144A(d)(4), unless the Company and the Guarantors furnish information to
     the Commission pursuant to Section 13 or 15(d) of the 1934 Act (such
     information, whether made available to holders or prospective purchasers or
     furnished to the Commission, is herein referred to as "Additional
     Information").

          (iv) Restriction on Repurchases.  Until the expiration of one year
     after the original issuance of the Securities and the Guarantees, the
     Company and the Guarantors will not, and will cause their respective
     Affiliates not to, purchase or agree to purchase or otherwise acquire any
     Securities or Guarantees which are "restricted securities" (as such term is
     defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial
     owner or otherwise (except as against acting as a securities broker on
     behalf of and for the account of customers in the ordinary course of
     business in unsolicited broker's transactions) unless, immediately upon any
     such purchase, the Company, the Guarantors or any Affiliate shall submit
     such Securities or Guarantees to the Trustee for cancellation.

     (c) Resale Pursuant to Rule 903 of Regulation S or Rule 144A.  Each Initial
Purchaser understands that the Securities and the Guarantees have not been and
will not be registered under the 1933 Act and may not be offered or sold within
the United States or to, or for the account or benefit of, U.S. persons except
in accordance with Regulation S under the 1933 Act or pursuant to an exemption
from the registration requirements of the 1933 Act.  Each Initial Purchaser
represents and agrees, that, except as permitted by Section 6(a) above, it has
offered and sold Securities and Guarantees and will offer and sell Securities
and Guarantees (i) as part of their

                                       23
<PAGE>
 
distribution at any time and (ii) otherwise until forty days after the later of
the date upon which the offering of the Securities and the Guarantees commences
and the Closing Time, only in accordance with Rule 903 of Regulation S or Rule
144A under the 1933 Act.  Accordingly, neither the Initial Purchasers, their
affiliates nor any persons acting on their behalf have engaged or will engage in
any directed selling efforts with respect to Securities and Guarantees, and the
Initial Purchasers, their affiliates and any person acting on their behalf have
complied and will comply with the offering restriction requirements of
Regulation S.  Each Initial Purchaser agrees that, at or prior to confirmation
of a sale of Securities and Guarantees (other than a sale of Securities and
Guarantees pursuant to Rule 144A), it will have sent to each distributor, dealer
or person receiving a selling concession, fee or other remuneration that
purchases Securities and Guarantees from it or through it during the restricted
period a confirmation or notice to substantially the following effect:

          "The Securities and Guarantees covered hereby have not been registered
          under the United States Securities Act of 1933 (the "Securities Act")
          and may not be offered or sold within the United States or to or for
          the account or benefit of U.S. persons (i) as part of their
          distribution at any time and (ii) otherwise until forty days after the
          later of the date upon which the offering of the Securities and the
          Guarantees commenced and the date of closing, except in either case in
          accordance with Regulation S or Rule 144A promulgated under the
          Securities Act.  Terms used above have the meaning given to them by
          Regulation S."

Terms used in the above paragraph have the meanings given to them by Regulation
S.

Each Initial Purchaser severally represents and agrees that it has not entered
and will not enter into any contractual arrangements with respect to the
distribution of the Securities, except with its affiliates or with the prior
written consent of the Company and the Guarantors.

     SECTION 7.  Indemnification.

     (a) Indemnification of Initial Purchasers.  The Company and each of the
Guarantors, jointly and severally, agree to indemnify and hold harmless each
Initial Purchaser and each person, if any, who controls any Initial Purchaser
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in any Preliminary Offering
     Memorandum or the Final Offering Memorandum (or any amendment or supplement
     thereto (including any document incorporated by reference into the
     Preliminary Offering Memorandum or Final Offering Memorandum)), or the
     omission or alleged

                                       24
<PAGE>
 
     omission therefrom of a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     7(d) below) any such settlement is effected with the written consent of the
     Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by Merrill Lynch), reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company or the
Guarantors by any Initial Purchaser through Merrill Lynch expressly for use in
the Offering Memorandum (or any amendment thereto) provided, further, that the
Company and the Guarantors will not be liable to the Initial Purchasers or any
person controlling such Initial Purchasers with respect to any such untrue
statement or alleged untrue statement or omission or alleged omission made in
any Preliminary Offering Memorandum to the extent that the Company and the
Guarantors shall sustain the burden of proving that any such loss, liability,
claim, damage or expense resulted from the fact that the Initial Purchaser sold
securities to a person to whom such Initial Purchaser failed to send or give, at
or prior to the written confirmation of the sale of such Securities, a copy of
the Final Offering Memorandum (as amended or supplemented) if the Company and
the Guarantors have previously furnished copies thereof to the Initial
Purchasers (sufficiently in advance of the Closing Time to allow for
distribution of the Final Offering Memorandum in a timely manner) and complied
with their obligations under Sections 3(b) and 3(c) hereof and the loss,
liability, claim, damage or expense of the Initial Purchasers resulted from an
untrue statement or omission or alleged untrue statement or omission of a
material fact contained in or omitted from such Preliminary Offering Memorandum
(as amended or supplemented) which was corrected in the final Offering
Memorandum (as amended or supplemented).

     (b) Indemnification of Company, Guarantors and Directors.  Each Initial
Purchaser severally agrees to indemnify and hold harmless the Company, the

                                       25
<PAGE>
 
Guarantors and their directors and each person, if any, who controls the Company
or the Guarantors within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Offering Memorandum in reliance upon
and in conformity with written information furnished to the Company or the
Guarantors by such Initial Purchaser through Merrill Lynch expressly for use in
the Offering Memorandum.

     (c) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In case any such action is brought against any indemnified party,
and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party; provided, however, that if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties.  After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 7 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by Merrill Lynch in the case of
subsection (a) of this Section 7, representing the indemnified parties under
such subsection (a) who are parties to such action or actions) or (ii) the
indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnified party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party

                                       26
<PAGE>
 
without the consent of the indemnifying party.  No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 7 or Section
8 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

     (d) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 7(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 8.  Contribution.  If the indemnification provided for in Section 7
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Guarantors on the one hand and the Initial Purchasers on the other hand from the
offering of the Securities and the Guarantees pursuant to this Agreement or (ii)
if the allocation provided by clause (i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company and
the Guarantors on the one hand and of the Initial Purchasers on the other hand
in connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received by the Company and the Guarantors on the one
hand and the Initial Purchasers on the other hand in connection with the
offering of the Securities and the Guarantees pursuant to this Agreement shall
be deemed to be in the same respective proportions as the total net proceeds
from the offering of the Securities and the Guarantees pursuant to this
Agreement (before deducting expenses) received by the Company and the Guarantors
and the total underwriting discount received by the Initial Purchasers, bear to
the aggregate initial offering price of the Securities and the Guarantees.

                                       27
<PAGE>
 
     The relative fault of the Company and the Guarantors on the one hand and
the Initial Purchasers on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Guarantors or by the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Company, the Guarantors and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 8 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 8.  The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
8 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 8, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities (including the Guarantees) underwritten by
it and distributed to the public were offered to the public exceeds the amount
of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 8, each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such Initial
Purchaser, and each director of the Company or any Guarantor, and each person,
if any, who controls the Company or any Guarantor within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company and such Guarantor.  The Initial Purchasers'
respective obligations to contribute pursuant to this Section 8 are several in
proportion to the principal amount of Securities (including the Guarantees) set
forth opposite their respective names in Schedule A hereto and not joint.

     SECTION 9.  Representations Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company or any of the Subsidiaries submitted
pursuant hereto, shall remain operative and in full force and effect, regardless
of any

                                       28
<PAGE>
 
investigation made by or on behalf of any Initial Purchaser or controlling
person, or by or on behalf of the Company or any Guarantor, and shall survive
delivery of the Securities (including the Guarantees) to the Initial Purchasers.

     SECTION 10.  Termination of Agreement.

     (a) Termination; General.  The Representative may terminate this Agreement,
by notice to the Company and the Guarantors, at any time at or prior to the
Closing Time (i) if there has been, since the time of execution of this
Agreement or since the respective dates as of which information is given in the
Offering Memorandum, any Material Adverse Effect, whether or not arising in the
ordinary course of business, or (ii) if there shall have occurred a downgrading
in the rating assigned to the Securities or the Guarantees or any of the
Company's or any Guarantor's other debt securities by any nationally recognized
securities rating agency, or if such securities rating agency shall have
publicly announced that it has under surveillance or review, with possible
negative implications, its rating of the Securities, the Guarantees or any of
the Company's or Guarantor's other debt securities or guarantees of debt
securities, or (iii) if there has occurred any material adverse change in the
financial markets in the United States or the international financial markets,
any outbreak of hostilities or escalation thereof or other calamity or crisis or
any change or development involving a prospective change in national or
international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the judgment of the Representative,
impracticable to market the Securities or the Guarantees or to enforce contracts
for the sale of the Securities or the Guarantees, or (iv) if trading in any
securities of the Company or any Guarantor has been suspended or limited by the
Commission or the New York Stock Exchange, or if trading generally on the
American Stock Exchange or the New York Stock Exchange or in the NASDAQ National
Market System has been suspended or limited, or minimum or maximum prices for
trading have been fixed, or maximum ranges for prices have been required, by any
of said exchanges or by such system or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority, or
(v) if a banking moratorium has been declared by either Federal or New York
authorities.

     (b) Liabilities.  If this Agreement is terminated pursuant to this Section,
such termination shall be without liability of any party to any other party
except as provided in Section 4 hereof, and provided further that Sections 7 and
8 shall survive such termination and remain in full force and effect.

     SECTION 11.  Default by One or More of the Initial Purchasers.  If one or
more of the Initial Purchasers shall fail at the Closing Time to purchase the
Securities which it or they are obligated to purchase under this Agreement (the
"Defaulted Securities"), the Representative shall have the right, but not the
obligation, within 24 hours thereafter, to make arrangements for one or more of
the non-defaulting Initial Purchasers, or any other Initial Purchasers, to
purchase all, but not less than all, of the Defaulted Securities in such amounts
as may be agreed upon and upon the terms herein set forth; if, however, the
Representative shall not have completed such arrangements

                                       29
<PAGE>
 
within such 24-hour period, then this Agreement shall terminate without
liability on the part of any non-defaulting Initial Purchaser.

     No action taken pursuant to this Section shall relieve any defaulting
Initial Purchaser from liability in respect of its default.

     In the event of any such default which does not result in a termination of
this Agreement, either the Representative, the Company or the Guarantors shall
have the right to postpone the Closing Time for a period not exceeding seven
days in order to reflect any required changes in the Offering Memorandum or in
any other documents or arrangement.  As used herein, the term "Initial
Purchaser" includes any person substituted for an Initial Purchaser under this
Section 11.

     SECTION 12.  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the Initial
Purchasers shall be directed to the Representative at North Tower, World
Financial Center, New York, New York 10281-1201, attention of Christopher
Turner, with a copy to Fulbright & Jaworski L.L.P., 1301 McKinney, Suite 5100,

Jessup LLP, 9401 Wilshire Boulevard, 9th Floor, Beverly Hills, California 90212,
attention of Bertram K. Massing.

     SECTION 13.  Parties.  This Agreement shall each inure to the benefit of
and be binding upon the Initial Purchasers, the Company and the Guarantors and
their respective successors.  Nothing expressed or mentioned in this Agreement
is intended or shall be construed to give any person, firm or corporation, other
than the Initial Purchasers, the Company and the Guarantors and their respective
successors and the controlling persons and officers and directors referred to in
Sections 7 and 8 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision herein contained.  This Agreement and all conditions and provisions
hereof are intended to be for the sole and exclusive benefit of the Initial
Purchasers, the Company and the Guarantors and their respective successors, and
said controlling persons and officers and directors and their heirs and legal
representatives, and for the benefit of no other person, firm or corporation.
No purchaser of Securities and Guarantees from any Initial Purchaser shall be
deemed to be a successor by reason merely of such purchase.

     SECTION 14.  GOVERNING LAW AND TIME.  THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.  EXCEPT AS
OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

     SECTION 15.  Effect of Headings.  The Article and Section headings herein

agreement among the Initial Purchasers, the Company and the Guarantors in

                     FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                 SECTION 5(a)


     (i) Each of the Company and each Guarantor has been duly incorporated (or
organized, as the case may be) and is validly existing as a corporation (or
limited partnership or limited liability company, as the case may be) in good
standing under the laws of its respective jurisdiction of incorporation (or
organization, as the case may be).  As used herein, the term "in good standing"
means that the entity in question has made all filings required to be made, and
paid all fees required to be paid in connection therewith, through the date
hereof, pursuant to the terms of the general corporation law (or other
applicable organizational statute) of its respective jurisdiction of
organization except, with respect to the Guarantors, where the failure to make
such filing or pay such fee would not have a Material Adverse Effect.

     (ii) Each of the Company and each Guarantor has the requisite corporate (or
partnership or limited liability company, as the case may be) power and
authority to own, lease and operate its respective properties and to conduct its
respective business as described in the Offering Memorandum and to enter into
and perform its respective obligations under each of the Purchase Agreement,
Registration Rights Agreement, Indenture, Securities, Guarantees, Exchange
Securities and DTC Agreement (collectively, the "Covered Instruments") to which
it is a party.

     (iii)  Each of the Company and each Guarantor is duly qualified to transact
business as a foreign corporation (or limited partnership or limited liability
company, as the case may be) in, and is in good standing under the laws of, all
jurisdictions where the ownership or leasing of its respective properties or the
conduct of its respective business requires such qualification, except where the
failure so to qualify or to be in good standing would not result in a Material
Adverse Effect.

     (iv) The shares of the issued and outstanding capital stock of the Company
have been duly authorized and validly issued and are fully paid and
nonassessable; and none of the outstanding shares of capital stock of the
Company was issued in violation of the statutory preemptive or other similar
statutory rights of any securityholder of the Company.

     (v) All the issued and outstanding shares of capital stock of each of the
corporate Guarantors have been duly authorized and validly issued, are fully
paid and nonassessable and are owned beneficially by the Company free and clear
of any security interest or any other security interests, liens, encumbrances,
equities or claims.
<PAGE>
 
     (vi) The partner interests in each Guarantor that is a limited partnership
and the membership interests in each Guarantor that is a limited liability
company have been validly issued and fully paid and are owned beneficially by
the Company, free and clear of any liens, claims, encumbrances or other similar
rights in favor of third parties.

     (vii)  The Purchase Agreement has been duly authorized, executed and
delivered by the Company and by each of the Guarantors.

     (viii)  The Registration Rights Agreement has been duly authorized,
executed and delivered by the Company and by each of the Guarantors, and
constitutes the valid and binding obligation of the Company and each of the
Guarantors, enforceable against the Company and each of the Guarantors in
accordance with its terms.

     (ix) The DTC Agreement has been duly authorized, executed and delivered by
the Company and constitutes the valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms.

     (x) The Indenture has been duly authorized, executed and delivered by the
Company and each of the Guarantors and constitutes the valid and binding
obligation of the Company and each of the Guarantors, enforceable against the
Company and each of the Guarantors in accordance with its terms.

     (xi) The Securities and the Guarantees are in the form contemplated by the
Indenture and have been duly authorized by the Company and each of the
Guarantors, and when executed by the Company and each of the Guarantors (as
applicable) and authenticated by the Trustee in the manner provided in the
Indenture and delivered against payment of the purchase price therefor, will
constitute valid and binding obligations of the Company and each Guarantor,
enforceable against the Company and each Guarantor in accordance with their
respective terms, and will be entitled to the benefits of the Indenture.

     (xii)  The Exchange Securities have been duly authorized, and when executed
by the Company and each of the Guarantors in exchange for the Securities and
Guarantees pursuant to the Exchange Offer, will constitute valid and binding
obligations of the Company and each Guarantor, enforceable against the Company
and each Guarantor in accordance with their respective terms.

     (xiii)  The Securities, the Guarantees, the Exchange Securities, the
Registration Rights Agreement and the Indenture conform in all material respects
to the descriptions thereof contained in the Offering Memorandum.

     (xiv)  The documents incorporated by reference in the Offering Memorandum
(the "Incorporated Documents") (other than the financial statements and
supporting schedules therein, as to which no opinion need be rendered), when
they were filed with the Commission or as subsequently amended, complied as to
form in all material

                                      A-2
<PAGE>
 
respects with the requirements of the 1934 Act and the rules and regulations of
the Commission thereunder.

     (xv) There is not pending or, to the best of our  knowledge, threatened any
action, suit, proceeding, inquiry or investigation, to which the Company or any
Subsidiary is a party, or to which the property of the Company or any Subsidiary
is subject, before or brought by any court or governmental agency or body, which
might reasonably be expected to result in a Material Adverse Effect, or which
might reasonably be expected to materially and adversely affect the properties
or assets thereof or the consummation of the transactions contemplated in the
Purchase Agreement or the performance by the Company or any Guarantor of its
respective obligations thereunder or under the Securities, the Guarantees or the
Exchange Securities.

     (xvi)  The information contained in the Offering Memorandum under the
captions "Risk Factors -- Impact of Government Regulation", "Risk Factors --
Failure to Comply With Governmental Regulations", "Business -- Environmental
Regulation", "Business -- Environmental Proceedings" and "Description of Certain
Other Indebtedness", to the extent that it constitutes matters of law, summaries
of legal matters, summaries of the Company's charter and bylaws and summaries of
legal proceedings, or legal conclusions, has been reviewed by us and is correct
in all material respects.

     (xvii)  Neither the Company nor any of the Guarantors is in violation of
its charter or bylaws (or if a partnership, limited liability company or other
legal entity, of its equivalent constituent documents), and, to the best of our
knowledge, no default by the Company or any of the Guarantors exists in the due
performance or observance of any obligation, agreement, covenant or condition
contained in any contract, indenture, mortgage, loan agreement, note, lease or
other agreement or instrument that is described or referred to in the Offering
Memorandum or filed or incorporated by reference as an exhibit to the Offering
Memorandum or any Incorporated Document, which default, singly or in the
aggregate, would have a Material Adverse Effect.

     (xviii)  All descriptions in the Offering Memorandum and in the documents
incorporated by reference therein of contracts and other documents to which the
Company, any Guarantor or any of their subsidiaries are a party are accurate in
all material respects; to the best of our knowledge, there are no franchises,
contracts, indentures, mortgages, loan agreements, notes, leases or other
instruments that would be required to be described in the Offering Memorandum
(assuming that the Offering Memorandum were included in a Registration Statement
on Form S-1) and in the documents incorporated by reference therein that are not
described or referred to in the Offering Memorandum or in the documents
incorporated by reference therein other than those described or referred to
therein, and the descriptions thereof or references thereto are correct in all
material respects.

                                      A-3
<PAGE>
 
     (xix)  No authorization, approval, consent, license, order, registration,
qualification or decree of any court or governmental authority or agency,
domestic or foreign, is necessary in connection with the due authorization,
execution and delivery of the Purchase Agreement or the due execution, delivery
or performance of the Indenture by the Company or any of the Guarantors or for
the offering, issuance, sale or delivery of the Securities and the Guarantees to
the Initial Purchasers or for the resale of the Securities and the Guarantees by
the Initial Purchasers in accordance with the Purchase Agreement and in the
manner contemplated by the Offering Memorandum, or for the performance by the
Company or any of the Guarantors of their respective obligations thereunder, in
connection with the offering, issuance or sale of the Securities and the
Guarantees pursuant to the Purchase Agreement and in the manner contemplated by
the Offering Memorandum or the consummation of the transaction contemplated by
the Covered Instruments (including the issuance and sale of the Securities and
the Guarantees and the use of proceeds from the sale of the Securities and the
Guarantees as described in the Offering Memorandum under the caption "Use of
Proceeds"), except, with respect to the consummation of the transactions
contemplated by the Registration Rights Agreement, such as have been obtained
and such as may be required under the 1933 Act or the Trust Indenture Act or
Blue Sky or other state securities laws, as to which we express no opinion.

     (xx) It is not necessary in connection with the offer, sale and delivery of
the Securities and the Guarantees to the Initial Purchasers and to each
Subsequent Purchaser, in each case in the manner contemplated by the Purchase
Agreement, the Registration Rights Agreement and the Offering Memorandum, to
register the Securities and the Guarantees under the 1933 Act or to qualify the
Indenture under the Trust Indenture Act.

     (xxi)  The execution, delivery and performance of each of the Covered
Instruments to which it is a party by each of the Company and each Guarantor,
the consummation of the transactions contemplated by the Purchase Agreement and
the Offering Memorandum (including the issuance and sale of the Securities and
Guarantees and the use of the proceeds from the sale of the Securities and
Guarantees as described in the Offering Memorandum under the caption "Use Of
Proceeds"), and compliance by the Company and the Guarantors with their
respective obligations under the terms of each the Covered Instruments:  (a)
have been duly authorized by all necessary corporate, partnership or limited
liability company action, as the case may be; (b) do not and will not, whether
with or without the giving of notice or the passage of time or both, conflict
with or constitute a breach of, or default or Repayment Event (as defined in
Section 1(a)(xiii) of the Purchase Agreement) under, or result in the creation
or imposition of any lien, charge or encumbrance upon any property or assets of
the Company or any Guarantor pursuant to, any contract, indenture, mortgage,
deed of trust, loan or credit agreement, note, lease or any other agreement or
instrument known to us, to which the Company or any Guarantor is a party or by
which it or any of them may be bound, or to which any of the property or assets
of the Company or any Guarantor is subject (except for such conflicts, breaches
or defaults or liens, charges or encumbrances that would not have a Material
Adverse Effect); and (c) will not result

                                      A-4
<PAGE>
 
in any violation of the provisions of the charter or by-laws or other
constituent documents of the Company or any Guarantor, or of any applicable law,
statute, rule, regulation, judgment, order, writ or decree of any government,
government instrumentality or court, domestic or foreign, having jurisdiction
over the Company or any Guarantor or any Subsidiary, or any of their respective
properties, assets or operations, to the extent such violation would result in a
Material Adverse Effect.

     (xxii)  Neither the Company nor any of the Guarantors is an "investment
company" or an entity "controlled" by an "investment company," as such terms are
defined in the 1940 Act.

     During the course of the preparation of the Offering Memorandum, we have
participated in conferences with certain officers and other representatives of
the Company at which the contents of the Offering Memorandum and related matters
were discussed.  Given the limitations inherent in the independent verification
of factual matters and the character of determinations involved in the offering
process, we are not passing upon and do not assume any responsibility for the
accuracy, completeness or fairness of any portion of the Offering Memorandum
(except to the extent set forth in paragraph (xvi) above), and we have not
independently verified the accuracy, completeness or fairness of any information
contained in the Offering Memorandum.  Subject to, and on the basis of the
foregoing, no facts have come to our attention that cause us to believe that, as
of the date of the Offering Memorandum, the Offering Memorandum contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or that, as of the date hereof, contains an untrue statement of a material fact
or omits to state a material fact necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, except that
we make no comment with respect to the financial statements, notes, schedules or
other financial data included or incorporated in or omitted from the Offering
Memorandum.

     In rendering such opinion, we are relying (A), to the extent that our
opinions with respect to enforceability given in paragraphs (viii), (ix), (x),
(xi) and (xii) involve matters governed by the laws of the State of New York, on
the opinion of Fulbright & Jaworksi L.L.P., addressed to the Initial Purchasers,
and (B), as to matters of fact (but not as to legal conclusions), to the extent
we deem proper, on certificates of responsible officers of the Company and
public officials.  Such opinion shall not state that it is to be governed or
qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation, the
Legal Opinion Accord of the ABA Section of Business Law (1991).

Dear Sirs:

We have audited the consolidated balance sheets of Newpark Resources, Inc.

consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1996, included in the 
Offering Memorandum for $125,000,000 of Newpark Resources, Inc. Senior 
Subordinated Notes (the Notes) due 2007.  Our report with respect thereto is 
included in the Offering Memorandum.  This Offering Memorandum, dated December 
10, 1997, is herein referred to as the Offering Memorandum.

This letter is being furnished in reliance upon your representation to us that--

     a.   You are knowledgeable with respect to the due diligence review process
          that would be performed if this placement of securities were being
          registered pursuant to the Securities Act of 1933 (the Act).

     b.   In connection with the offering of the Notes, the review process you
          have performed is substantially consistent with the due diligence
          review process that you would have performed if this placement of
          securities were being registered pursuant to the Act.

In connection with the Offering Memorandum--

     1.   We are independent certified public accountants with respect to the
          Company within the meaning of the Act and the applicable published
          rules and regulations thereunder.

     3.   We have not audited any financial statements of the Company as of any
          date or for any period subsequent to December 31, 1996; although we
          have conducted an audit for the year ended December 31, 1996, the
          purpose (and therefore the scope) of the audit was to enable us to
          express our opinion on the financial statements as of December 31,
          1996, and for the year then ended, but not on the financial statements
          for any interim period within that year. Therefore, we are unable to
          express any opinion on the unaudited consolidated balance sheet as of
          September 30, 1997, and the unaudited consolidated statement of
          income, stockholders' equity, and cash flows for the nine-month
          periods ended September 30, 1997 and 1996, included in the Offering
          Memorandum, or on the financial position, results of operations, or
          cash flows as of any date or for any period subsequent to December 31,
          1996.

     4.   For purpose of this letter, we have read the 1997 minutes of meetings
          of the stockholders and the board of directors of the Company as set
          forth in the minute books as of September 17, 1997, officials of the
          Company having advised us that the minutes of all such meetings
          through that date were set forth therein; we have carried out other
          procedures to December 8, 1997, as follows (our work did not extend to
          the period from December 9, 1997, to December 10, 1997, inclusive):

          a.  With respect to the nine-month periods ended September 30, 1997 
              and 1996, we have--

              (i)   Performed the procedures specified by the American Institute
                    of Certified Public Accountants for a review of interim
                    financial information as described in SAS No. 71, Interim
                    Financial Information, on the unaudited consolidated balance
                    sheet as of September 30, 1997, and unaudited consolidated
                    statements of income, stockholders' equity, and cash flows
                    for the nine-month periods ended September 30, 1997 and
                    1996, included in the Offering Memorandum.

              (ii)  Inquired of certain officials of the Company who have
                    responsibility for financial and accounting matters whether
                    the unaudited consolidated financial statements referred to
                    in a(i) comply as to form in all material respects with the
                    applicable accounting requirements of the Act and the
                    related published rules and regulations.

          b.  With respect to the period from October 1, 1997 to October 31, 
              1997, we have--

              (i)   Read the unaudited consolidated financial statements of the
                    Company and subsidiaries for October 1997 furnished us by
                    the Company, officials of the Company having advised us that
                    no such financial statements as of any date for any period
                    subsequent to October 31, 1997, were available.

              (ii)  Inquired of certain officials of the Company who have
                    responsibility for financial and accounting matters whether
                    the unaudited consolidated financial statements referred to
                    in b(i) are stated on a basis substantially consistent with
                    that of the audited consolidated financial statements
                    included in the Offering Memorandum.

The foregoing procedures do not constitute an audit conducted in accordance with
generally accepted auditing standards.  Also, they would not necessarily reveal 
matters of significance with respect to the comments in the following paragraph.
Accordingly, we make no representations regarding the sufficiency of the 
foregoing procedures for your purposes.


                                      -2-

5. Nothing came to our attention as a result of the foregoing procedures, 
   however, that caused us to believe that:

   a. (i)  Any material modifications should be made to the unaudited
           consolidated financial statements described in 4a(i), included in the
           Offering Memorandum, for them to be in conformity with generally
           accepted accounting principles.

      (ii) The unaudited consolidated financial statements described in 4a(i) do
           not comply as to form in all material respects with the applicable
           accounting requirements of the Act and the related published rules
           and regulations.

   b. (i)  At October 31, 1997, there was any change in the capital stock,
           increase in short-term indebtedness or long-term debt, or decrease in
           consolidated net current assets or stockholders' equity of the
           consolidated Company as compared with amounts shown in the September
           30, 1997, unaudited consolidated balance sheet included in the
           Offering Memorandum, except as follows (in thousands of dollars):

                                   September 30,  October 31,
                                       1997          1997     Increase  Decrease

           Capital stock             $   634       $   634     $   --     $ --
           Short-term indebtedness     1,650         1,247         --      403
           Long-term debt             76,392        80,092      3,700       --
           Net current assets         88,257        89,473      1,216       --

      (ii) For the period from October 1, 1997 to October 31, 1997, there were
           any decreases, as compared to the corresponding period in the
           preceding year, in consolidated net sales, consolidated operating
           income or in the total or per-share amounts of consolidated net
           income, except in all instances for changes, increases, or decreases
           that the Offering Memorandum discloses have occurred or may occur.

6. As mentioned in 4b, Company officials have advised us that no consolidated
   financial statements as of any date or for any period subsequent to October
   31, 1997, are available; accordingly, the procedures carried out by us with
   respect to changes in financial statement items after October 31, 1997, have,
   of necessity, been even more limited than those with respect to the periods
   referred to in 4. We have inquired of certain officials of the Company who
   have responsibility for financial and accounting matters whether at December
   8, 1997 there was any change in the capital stock, increase in short-term
   indebtedness or long-term debt of the consolidated Company as compared with
   amounts shown on the September 30, 1997, unaudited consolidated balance sheet
   of the Company included in the Offering Memorandum. We have been informed by
   officials of the Company that they believe: (1) capital stock, as described
   in 5b(i), has not changed from September 30, 1997 to December 8, 1997, (2)
   the decrease in short-term indebtedness, as described in 5b(i), continues in
   substantially the same amount at December 8, 1997, and (3) the increase in
   long-term debt, as described in 5b(i), from September 30, 1997 to December 8,
   1997 is approximately $16.1 million.

                                      -3-

 7. For purposes of this letter, we have also read the items identified by you
    on the attached copy of the Offering Memorandum, Form 10-K, Form 10-K/A, and
    the definitive proxy materials and have performed the following procedures,
    which were applied as indicated with respect to the symbols explained below:

       Compared the amount with the Company's audited financial statements for
       the period indicated contained in the Offering Memorandum and found them
       to be in agreement.

       Compared the amount with the Company's audited financial statements for
       the period indicated and found them to be in agreement after giving
       effect to the following: (1) a 2-for-1 stock split approved by the board
       of directors on October 27, 1997, (2) a 2-for-1 stock split approved by
       the board of directors on May 14, 1997, (3) a 5% stock dividend declared
       and paid in 1995, and (4) restatement of amounts due to a transaction on
       February 28, 1997 that was accounted for as a pooling of interests.

       Compared to the amount with a schedule or report prepared by the Company
       and found them to be in agreement. Amounts appearing in such schedule or
       report were compared with accounting records of the Company and found to
       be in agreement.

       Proved the arithmetic accuracy of the amounts, percentages or per share 
       information based upon data contained in the Offering Memorandum.

 8. Our audits of the consolidated financial statements for the Company for the
    periods referred to in the introductory paragraph of this letter comprised
    audit tests and procedures deemed necessary for the purpose of expressing an
    opinion on such financial statements taken as a whole. For none of the
    periods referred to therein, or any other period, did we perform audit tests
    for the purpose of expressing an opinion on individual balances of accounts
    or summaries of selected transactions such as those enumerated above, and,
    accordingly, we express no opinion thereon.

 9. It should be understood that we make no representations regarding questions
    of legal interpretation or regarding the sufficiency for your purposes of
    the procedures enumerated in the preceding paragraph; also, such procedures
    would not necessarily reveal any material misstatement of the amounts or
    percentages listed above. Further, we have addressed ourselves solely for
    the foregoing data as set forth in the Offering Memorandum and make no
    representations regarding the adequacy of disclosure or regarding whether
    any material facts have been omitted.

10. This letter is solely for the information of the addressees and to assist
    the initial purchasers in conducting and documenting their investigation of
    the affairs of the Company in connection with the offering of the Notes
    covered by the Offering Memorandum and it is not to be used, circulated,
    quoted, or otherwise referred to for any purpose, including but not limited
    to the purchase or sale of the Notes, nor is it to be filed with or referred
    to in whole or in part in the Offering Memorandum or any other document,
    except that reference may be made to it in the purchase agreement or in any
    list of closing documents pertaining to the offering of the Notes covered by
    the Offering Memorandum.

Very truly yours,

     The undersigned hereby acknowledges receipt and review of the Prospectus
dated _________, 1998 (the "Prospectus") of Newpark Resources, Inc., a Delaware
corporation (the "Company"), and this Letter of Transmittal (the "Letter of
Transmittal"), which together constitute the Company's offer (the "Exchange
Offer") to exchange its 8 5/8% Senior Subordinated Notes Due 2007, Series B (the
"Exchange Notes"), the issuance of which has been registered under the
Securities Act of 1933, as amended (the "Securities Act"), pursuant to a
Registration Statement of which the Prospectus is a part, for a like principal
amount of its outstanding 8 5/8% Senior Subordinated Notes Due 2007, Series A
(the "144A Notes"), upon the terms and subject to the conditions set forth in
the Prospectus. Capitalized terms used but not defined herein have the
respective meanings given to them in the Prospectus.

     The Company reserves the right, at any time or from time to time, to extend
the Exchange Offer at its discretion, in which event the term "Expiration Date"
shall mean the latest date to which the Exchange Offer is extended.  The Company
will notify the Exchange Agent of any extension by oral or written notice and
will make a public announcement thereof, each prior to 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.

     Registered Holders of Exchange Notes on the relevant record date for the
first interest payment date following the consummation of the Exchange Offer
will receive interest accruing from the most recent date to which interest has
been paid on the 144A Notes or, if no interest has been paid, from December 17,
1997. 144A Notes accepted for exchange will cease to accrue interest from and
after the date of consummation of the Exchange Offer. Holders whose 144A Notes
are accepted for exchange will not receive any payment in respect of accrued
interest on such 144A Notes otherwise payable on any interest payment date the
record date for which occurs on or after consummation of the Exchange Offer.

     This Letter of Transmittal is to be used either if (i) certificates
representing 144A Notes are to be physically delivered to State Street Bank and
Trust Company (the "Exchange Agent") herewith by Holders, (ii) tender of 144A
Notes is to be made by book-entry transfer to an account maintained by the
Exchange Agent at The Depository Trust Company (the "Depository"), pursuant to
the procedures set forth in "The Exchange Offer -- Procedures for Tendering" in
the Prospectus by any financial institution that is a participant in the
Depository and whose name appears on a security position listing as the owner of
144A Notes, or (iii) tender of 144A Notes is to be made according to the
guaranteed delivery procedures set forth in the Prospectus under "The Exchange
Offer--Guaranteed Delivery Procedures."  Even if the tender of 144A Notes is
made by book-entry transfer, delivery of this Letter of Transmittal and any
other required documents must be made to the Exchange Agent.

           DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY
              DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     The term "Holder" with respect to the Exchange Offer means any person in
whose name 144A Notes are registered on the books of the Company or any other
person who has obtained a properly completed assignment from the registered
holder or any participant in the Depository's system whose name appears on a
security position as the holder of such 144A Notes and who desires to deliver
144A Notes by book-entry transfer at the Depository. All Holders of 144A Notes
who wish to tender their 144A Notes must, prior to the Expiration Date: (i)
complete, sign and deliver this Letter of Transmittal, or a facsimile thereof,
to the Exchange Agent, in person or to the address set forth above, and (ii)
tender (and not withdraw) their 144A Notes or, if a tender of 144A Notes is to
be made by book-entry transfer to the account maintained by the Exchange Agent
at the Depository, confirm such book-entry transfer, in each case in accordance
with the procedures for tendering described in the Prospectus and the
Instructions to this Letter of Transmittal. Holders of 144A Notes whose
certificates are not immediately available, or who are unable to deliver their

                                      -2-
<PAGE>
 
certificates or book-entry confirmation and all other documents required by this
Letter of Transmittal to be delivered to the Exchange Agent on or prior to the
Expiration Date, may tender their 144A Notes according to the guaranteed
delivery procedures set forth under the caption "The Exchange Offer--Guaranteed
Delivery Procedures" in the Prospectus. See Instruction 2.

     The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with respect
to the Exchange Offer.  Holders who wish to tender their 144A Notes must
complete this Letter of Transmittal in its entirety.

     For purposes of the Exchange Offer, the Company shall be deemed to have
accepted for exchange validly tendered 144A Notes when, as and if the Company
has given oral or written notice thereof to the Exchange Agent.  Any tendered
144A Notes that are not accepted for exchange pursuant to the Exchange Offer for
any reason will be returned (except as otherwise indicated below with respect to
tenders through the Depository), without expense, to the undersigned at the
address shown below or at a different address as may be indicated herein under
"Special Delivery Instructions", as promptly as practicable after the Expiration
Date.

Ladies and Gentlemen:

     Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company for exchange the principal amount of 144A Notes
indicated above.  Subject to and effective upon the acceptance for exchange of
the principal amount of 144A Notes tendered in accordance with this Letter of
Transmittal, the undersigned hereby exchanges, assigns and transfers to, or upon
the order of, the Company all right, title and interest in and to the 144A Notes
tendered for exchange hereby, including all rights to accrued and unpaid
interest thereon as of the Expiration Date.  The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent the true and lawful agent and
attorney-in-fact for the undersigned (with full knowledge that said Exchange
Agent also acts as the agent for the Company in connection with the Exchange
Offer) with respect to the tendered 144A Notes with full power of substitution,
subject only to the right of withdrawal described in the Prospectus, to (i)
deliver such 144A Notes, or transfer ownership of such 144A Notes on the account
books maintained by the Depository, to the Company and deliver all accompanying
evidences of transfer and authenticity, and (ii) present such 144A Notes for
transfer on the books of the Company and receive all benefits and otherwise
exercise all rights of beneficial ownership of such 144A Notes, all in
accordance with the terms of the Exchange Offer.  The power of attorney granted
in this paragraph shall be deemed to be irrevocable and coupled with an
interest.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the 144A Notes
tendered hereby and to acquire the Exchange Notes issuable upon the exchange of
such tendered 144A Notes, and that the Company will acquire good and
unencumbered title thereto, free and clear of all liens, restrictions, charges
and encumbrances and not subject to any adverse claim, when the same are
accepted for exchange by the Company. The undersigned hereby further represents
that (i) the Exchange Notes to be acquired pursuant to this letter are being
acquired in the ordinary course of business of the person receiving such
Exchange Notes, whether or not such person is the undersigned, (ii) neither the
undersigned nor any such other person is engaged in, intends to engage in or has
any arrangement or understanding with any person to participate in the
distribution of such Exchange Notes, and (iii) neither the undersigned nor any
such person is an "affiliate," as defined in Rule 405 under the Securities Act
of 1933, as amended (the "Securities Act"), of the Company. If the undersigned
is a broker-dealer, the undersigned further represents that (i) it acquired the
144A Notes for its own account as a result of market-making activities or other
trading activities, and (ii) it has not entered into any arrangement or

                                      -5-
<PAGE>
 
understanding with the Company or any "affiliate" thereof (within the meaning of
Rule 405 under the Securities Act) to distribute the Exchange Notes to be
received in the Exchange Offer.

     The undersigned also acknowledges that the Exchange Offer is being made in
reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, including Exxon Capital Holdings Corporation (available May 13, 1988),
Morgan Stanley & Co. Incorporated (available June 5, 1991), Sherman & Sterling
(available July 2, 1993) and similar no-action letters (the "Prior No-Action
Letters"), that the Exchange Notes issued pursuant to the Exchange Offer in
exchange for the 144A Notes may be offered for resale, resold and otherwise
transferred by Holders thereof (other than (i) a broker-dealer who purchased
such 144A Notes directly from the Company for resale pursuant to Rule 144A or
any other available exemption under the Securities Act or (ii) a person that is
an "affiliate" (within the meaning of Rule 405 of the Securities Act) of the
Company), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such Exchange Notes are acquired
in the ordinary course of such Holders' business and such Holders are not
participating, and have no arrangement or understanding with any person to
participate, in a distribution of such Exchange Notes.  However, the SEC has not
considered the Exchange Offer in the context of a no-action letter, and there
can be no assurance that the staff of the SEC would make a similar determination
with respect to the Exchange Offer as in other circumstances.  If the
undersigned is not a broker-dealer, the undersigned represents that it is not
engaged in, and does not intend to engage in, a distribution of Exchange Notes.
If the undersigned is a broker-dealer that is receiving the Exchange Notes for
its own account in exchange for 144A Notes that were acquired as a result of
market-making activities or other trading activities, it acknowledges that it
will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such Exchange Notes; however, by so acknowledging
and by delivering a prospectus, the undersigned will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.  The
undersigned and any other person receiving the Exchange Notes covered by this
letter acknowledge that, if they are participating in the Exchange Offer for the
purpose of distributing the Exchange Notes, they cannot rely on the position of
the staff of the SEC enunciated in the Prior No-Action Letters and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction. 

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the exchange, assignment and transfer of the 144A Notes
tendered hereby, including the transfer of such 144A Notes on the account books
maintained by the Depository.

     The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offer--Conditions."  The undersigned
acknowledges that as a result of these conditions (which may be waived, in whole
or in part, by the Company), as more particularly set forth in the Prospectus,
the Company may not be required to exchange any of the 144A Notes tendered
hereby, and, in such event, the 144A Notes not exchanged will be returned
(except as noted below with respect to tenders through the Depository) to the
undersigned at the address shown below or at such different address as may be
indicated herein under "Special Delivery Instructions", as promptly as
practicable after the Expiration Date.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators, trustees in bankruptcy and legal representatives of the
undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned.  The undersigned acknowledges that this tender
may be withdrawn only in accordance with the procedures set forth in "The
Exchange Offer--Withdrawal Rights" section of the Prospectus and in Instruction
14.

     The undersigned acknowledges that the Company's acceptance of properly
tendered 144A Notes  pursuant to the procedures described under the caption "The
Exchange Offer--Procedures for Tendering" in the Prospectus and in the
instructions hereto will constitute a binding agreement between the undersigned
and the Company upon the terms and subject to the conditions of the Exchange
Offer.  The undersigned further agrees that acceptance of any tendered 144A
Notes by the Company and the issuance of Exchange Notes in exchange therefor
shall constitute performance in full by the Company of its obligations under the
Registration Agreement and that the Company shall have no further obligations or
liabilities thereunder for the registration of the 144A Notes or the Exchange
Notes.

     Unless otherwise indicated under "Special Issuance Instructions," please
issue the Exchange Notes issued in exchange for the 144A Notes accepted for
exchange and return any 144A Notes not tendered or not exchanged, in the name(s)
of the undersigned (or, in the case of 144A Notes tendered by book-entry
transfer, by crediting the DTC account number set forth above).  Similarly,
unless otherwise indicated under "Special Delivery Instructions," please mail or
deliver the Exchange Notes issued in exchange for the 144A Notes accepted for
exchange and any 144A Notes not tendered or not exchanged (and accompanying
documents, as appropriate) to the undersigned at the address shown below the
undersigned's signature(s) (unless tender is being made through book-entry
transfer).  If both "Special Issuance Instructions" and "Special Delivery
Instructions" are completed, please issue the Exchange Notes issued in exchange
for the 144A Notes accepted for exchange in the name(s) of, and return any 144A
Notes not tendered or not exchanged to, the person(s) so indicated.  The
undersigned recognizes that the Company has no obligation pursuant to the
"Special Issuance Instructions" and "Special Delivery Instructions" to transfer
any 144A Notes from the name of the registered holder(s) thereof if the Company
does not accept for exchange any of the 144A Notes so tendered for exchange.

THAN AS SET FORTH HEREIN, OR INSTRUCTIONS VIA A FACSIMILE NUMBER OTHER THAN THE
ONE SET FORTH HEREIN, WILL NOT CONSTITUTE A VALID DELIVERY.

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their 144A
Notes and whose 144A Notes are not immediately available or who cannot deliver
their 144A Notes, this Letter of Transmittal or any other documents required
hereby to the Exchange Agent prior to the Expiration Date or who cannot complete
the procedure for book-entry transfer on a timely basis, must tender their 144A
Notes according to the guaranteed delivery procedures set forth in the
Prospectus.  Pursuant to such procedures: (i) such tender must be made by or
through a firm which is a member of a registered national securities exchange or
of the National Association of Securities Dealers, Inc., a commercial bank or a
trust company having an office or correspondent in the United States or an
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Exchange Act (an "Eligible Institution"); (ii) prior to the Expiration Date, the
Exchange Agent must have received from the Eligible Institution a properly
completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, mail or hand delivery) setting forth the name and address of the
holder of the 144A Notes, the registration number(s) of such 144A Notes and the
total principal amount of 144A Notes tendered, stating that the tender is being
made thereby and guaranteeing that, within the three New York Stock Exchange
trading days after the date of execution of the Notice of Guaranteed Delivery,
this Letter of Transmittal (or facsimile hereof), together with the 144A Notes
in proper form for transfer (or a confirmation of book-entry transfer of such
144A Notes into the Exchange Agent's account at the Depository) and any other
documents required hereby, will be deposited by the Eligible Institution with
the Exchange Agent; and (iii) the certificates for all physically tendered
shares of 144A Notes, in proper form for transfer (or book-entry confirmation,
as the case may be), and all other documents required hereby must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
date of execution of the Notice of Guaranteed Delivery.

     Any holder of 144A Notes who wishes to tender 144A Notes pursuant to the
guaranteed delivery procedures described above must ensure that the Exchange
Agent receives the Notice of Guaranteed Delivery prior to 5:00 p.m., New York
City time, on the Expiration Date.  Upon request of the Exchange Agent, a Notice
of Guaranteed Delivery will be sent to holders who wish to tender their 144A
Notes according to the guaranteed delivery procedures set forth above.

     See "The Exchange Offer--Guaranteed Delivery Procedures" section of the
Prospectus.

     3.   TENDER BY HOLDER.  Only a holder of 144A Notes may tender such 144A
Notes in the Exchange Offer.  Any beneficial holder of 144A Notes who is not the
registered holder and who wishes to tender should arrange with the registered
holder to execute and deliver this Letter of Transmittal on its behalf or must,
prior to completing and executing this Letter of Transmittal and delivering its
144A Notes, either make appropriate arrangements to register ownership of the
144A Notes in such holder's name or obtain a properly completed assignment from
the registered holder.  The transfer of record ownership may take considerable
time, and completion of such transfer prior to the Expiration Date may not be
possible.

     4.   PARTIAL TENDERS.  Tenders of 144A Notes will be accepted only in
integral multiples of $1,000.  If less than the entire principal amount of any
144A Notes is tendered, the tendering holder should fill in the principal amount
tendered in the last column of the box entitled "Description of 144A Notes
Tendered" above.  The entire principal amount of 144A Notes delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
If the entire principal amount of all 144A Notes is not tendered, then 144A
Notes for the principal amount of 144A Notes not tendered and Exchange Notes
issued in exchange for any 144A Notes accepted will be sent to the holder at its
registered address, unless 

                                      -11-
<PAGE>
 
a different address is provided in the appropriate box on this Letter of
Transmittal or unless tender is made through the Depository, promptly after the
144A Notes are accepted for exchange.

     5.   SIGNATURES ON THIS LETTER OF TRANSMITTAL; ASSIGNMENTS AND 
ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal (or
facsimile hereof) is signed by the record holder(s) of the 144A Notes tendered
hereby, the signature must correspond with the name(s) as written on the face of
the 144A Notes without alteration, enlargement or any change whatsoever.

     If any of the 144A Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

     If a number of 144A Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many separate copies of this
Letter of Transmittal as there are different registrations of 144A Notes.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered holder or holders of 144A Notes listed and tendered hereby and the
Exchange Notes issued in exchange therefor are to be issued (or any untendered
principal amount of 144A Notes is to be reissued) to the registered holder, the
said holder need not and should not endorse any tendered 144A Notes, nor provide
a separate assignment. In any other case, such holder must either properly
endorse the 144A Notes tendered or transmit a properly completed assignment with
this Letter of Transmittal (in either case, executed exactly as the name(s) of
the registered holder(s) appear(s) on the 144A Notes), with the signatures on
the endorsement or assignment guaranteed by an Eligible Institution (except
where the 144A Notes are tendered for the account of an Eligible Institution).

     If this Letter of Transmittal (or facsimile hereof) or any 144A Notes or
assignments are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and,
unless waived by the Company, evidence satisfactory to the Company of their
authority to act must be submitted with this Letter of Transmittal.

     Endorsements on 144A Notes or signatures on assignments required by this
Instruction 5 must be guaranteed by an Eligible Institution, except as noted
below.

     NO SIGNATURE GUARANTEE IS REQUIRED IF (I) THIS LETTER OF TRANSMITTAL (OR
FACSIMILE HEREOF) IS SIGNED BY THE REGISTERED HOLDER(S) OF THE 144A NOTES
TENDERED HEREIN AND THE EXCHANGE NOTES ARE TO BE ISSUED DIRECTLY TO SUCH
REGISTERED HOLDER(S) AND NEITHER THE BOX ENTITLED "SPECIAL DELIVERY
INSTRUCTIONS" NOR THE BOX ENTITLED "SPECIAL REGISTRATION INSTRUCTIONS" HAS BEEN
COMPLETED, OR (II) SUCH 144A NOTES ARE TENDERED FOR THE ACCOUNT OF AN ELIGIBLE
INSTITUTION.  IN ALL OTHER CASES, ALL SIGNATURES ON THIS LETTER OF TRANSMITTAL
(OR FACSIMILE HEREOF) MUST BE GUARANTEED BY AN ELIGIBLE INSTITUTION.

     6.   SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.  Tendering holders
should indicate, in the applicable box or boxes, the name and address (or
account at the Depository) to which Exchange Notes or substitute 144A Notes for
principal amounts not tendered or not accepted for exchange are to be issued or
sent (or deposited), if different from the name and address of the person
signing this Letter 

                                      -12-
<PAGE>
 
of Transmittal. In the case of issuance in a different name, the taxpayer
identification or social security number of the person named must also be
indicated.

     7.   TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the exchange of 144A Notes pursuant to the Exchange Offer. If,
however, Exchange Notes or 144A Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered holder of the 144A Notes
tendered hereby, or if tendered 144A Notes are registered in the name of any
person other than the person signing this Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of 144A Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or any other person) will be payable
by the tendering holder.  If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with this Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering holder.

     8.   TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a
holder tendering 144A Notes must provide the Company (as payor) with its correct
taxpayer identification number ("TIN"), which, in the case of a holder who is an
individual is his or her social security number.  If the Company is not provided
with the correct TIN, the holder may be subject to a $50 penalty imposed by
Internal Revenue Service and backup withholding of 31% on interest payments on
the Exchange Notes.

     To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of failure
to report all interest or dividends, or (ii) the Internal Revenue Service has
notified the holder that such holder is no longer subject to backup withholding.
If the Exchange Notes will be registered in more than one name or will not be in
the name of the actual owner, consult the instructions on Internal Revenue
Service Form W-9, which may be obtained from the Exchange Agent, for information
on which TIN to report.

     If the tendering holder has not been issued a TIN and has applied for one,
or intends to apply for one in the near future, such holder should write
"Applied For" in the space provided for the TIN in Part 1 of the Substitute Form
W-9, sign and date the Substitute Form W-9 and sign the Certificate of Payee
Awaiting Taxpayer Identification Number.  If "Applied For" is written in Part 1,
the Company (or the Paying Agent under the Indenture governing the Exchange
Notes) shall retain 31% of payments made to the tendering holder during the
sixty-day period following the date of the Substitute Form W-9.  If the holder
furnishes the Exchange Agent or the Company with its TIN within sixty days after
the date of the Substitute Form W-9, the Company (or the Paying Agent) shall
remit such amounts retained during the sixty-day period to the holder, and no
further amounts shall be retained or withheld from payments made to the holder
thereafter.  If, however, the holder has not provided the Exchange Agent or the
Company with its TIN within such sixty-day period, the Company (or the Paying
Agent) shall remit such previously retained amounts to the IRS as backup
withholding.

     Certain holders (including, among others, all domestic corporations and
certain foreign individuals and foreign entities) are not subject to these
backup withholding and reporting requirements.  Such a holder, who satisfies one
or more of the conditions set forth in Part 2 of the Substitute Form W-9, should
execute the certification following such Part 2.  In order for a foreign holder
to qualify as an exempt recipient, the holder must submit to the Exchange Agent
a properly completed Internal Revenue Service Form W-8, signed 

                                      -13-
<PAGE>
 
under penalties of perjury, attesting to that holder's exempt status. A form W-8
can be obtained from the Exchange Agent.

     If backup withholding applies, the Exchange Agent is required to withhold
31% of any amounts otherwise payable to the holder.  Backup withholding is not
an additional tax.  Rather the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld.  If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.

     The Company reserves the right in its sole discretion to take whatever
steps are necessary to comply with the Company's obligations regarding backup
withholding.

     9.   VALIDITY AND FORM. All questions as to the validity, form, eligibility
(including time of receipt) and acceptance and withdrawal of tendered 144A Notes
will be determined by the Company in its sole discretion, which determination
shall be final and binding. The Company reserves the absolute right to reject
any and all 144A Notes not properly tendered or any 144A Notes the Company's
acceptance of which would, in the opinion of the Company or its counsel, be
unlawful. The Company also reserves the absolute right to waive any conditions
of the Exchange Offer or defects or irregularities in tenders as to particular
144A Notes. All tendering holders, by execution of this Letter of Transmittal
(or facsimile thereof), shall waive any right to receive notice of the
acceptance of the 144A Notes for exchange. The Company's interpretation of the
terms and conditions of the Exchange Offer (including this Letter of Transmittal
and the instructions hereto) shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of 144A Notes
must be cured within such time as the Company shall determine. Neither the
Company, the Exchange Agent nor any person shall be under any duty to give
notification of defects or irregularities with regard to tenders of 144A Notes
nor shall any of them incur any liability for failure to give such notification.
Tenders of 144A Notes will not be deemed to have been made until such defects or
irregularities have been cured to the Company's satisfaction or waived. Any 144A
Notes received by the Exchange Agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering holders, unless otherwise
provided in this Letter of Transmittal, as soon as practicable following the
Expiration Date. The Exchange Agent has no fiduciary duties to the holders with
respect to the Exchange Offer and is acting solely on the basis of directions of
the Company.

     10.  WAIVER OF CONDITIONS.  The Company reserves the absolute right to
waive, in whole or part, any of the conditions to the Exchange Offer set forth
in the Prospectus.

     11.  NO CONDITIONAL TENDER.  No alternative, conditional, irregular or
contingent tender of 144A Notes will be accepted.

     12.  MUTILATED, LOST, STOLEN OR DESTROYED 144A NOTES.  Any holder whose
144A Notes have been mutilated, lost, stolen or destroyed should contact the
Exchange Agent at the address indicated above for further instructions.

     13.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
or for additional copies of the Prospectus or this Letter of Transmittal may be
directed to the Exchange Agent at the address or telephone number set forth on
the cover page of this Letter of Transmittal.  Holders may also contact their
broker, dealer, commercial bank, trust company or other nominee for assistance
concerning the Exchange Offer.

     14.  WITHDRAWAL.  Except as otherwise provided herein, tenders of 144A
Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on
the Expiration Date.  To withdraw a tender of 144A Notes pursuant to the
Exchange Offer, a written or facsimile transmission notice of withdrawal must be
received by the Exchange Agent at the address set forth herein prior to 5:00
p.m., New York City time, on the Expiration Date.  Any such notice of withdrawal
must (i) specify the name of the person having deposited the 144A Notes to be
withdrawn (the "Depositor"), (ii) identify the 144A Notes to be withdrawn
(including the certificate or registration number(s) and principal amount of
such 144A Notes, or, in the case of notes transferred by book-entry transfer,
the name and number of the account at the Depository to be credited), (iii) be
signed by the Depositor in the same manner as the original signature on the
Letter of Transmittal by which such 144A Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the 144A Notes register the
transfer of such 144A Notes in the name of the Depositor withdrawing the tender,
(iv) specify the name in which any such 144A Notes are to be registered, if
different from that of the Depositor, and (v) include a statement that such
Holder is withdrawing such Holder's election to have such 144A Notes exchanged.

     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, whose
determinations shall be final and binding on all parties.  Any 144A Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer, and no Exchange Notes will be issued with respect thereto unless
the 144A Notes so withdrawn are validly retendered.  Properly withdrawn 144A
Notes may be retendered by following one of the procedures described in the
Prospectus under "The Exchange Offer--Procedures for Tendering" at any time
prior to the Expiration Date.

IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE HEREOF
(TOGETHER WITH THE 144A NOTES DELIVERED BY BOOK-ENTRY TRANSFER OR IN ORIGINAL
HARD COPY FORM) MUST BE RECEIVED BY THE EXCHANGE AGENT, OR THE NOTICE OF
GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT, PRIOR TO THE
EXPIRATION DATE.
